ETSI EN 302 217-4-1 V1.3.1 (2009-03) - Fixed Radio Systems; Characteristics and requirements for point-to-point equipment and antennas; Part 4-1: System-dependent requirements for antennas
SIST EN 302 217-4-1 V1.3.1:2009 is the Slovenian adoption of ETSI EN 302 217-4-1 V1.3.1, published by SIST. It specifies system-dependent characteristics and limits for single main beam, linear polarization, directional antennas used with point-to-point Fixed Radio Systems (FRS) in the 1 GHz to 86 GHz range. Engineers, purchasers and conformity teams use it to classify antennas, compare radiation pattern and cross-polar performance, and understand which antenna data belong in system design, frequency planning and product declaration.
What does SIST EN 302 217-4-1 V1.3.1:2009 specify?
SIST EN 302 217-4-1 V1.3.1:2009 specifies how point-to-point antennas are classified and what antenna characteristics are described for Fixed Radio Systems. It covers single polarization antennas, dual polarization antennas, dual band/single polarized antennas and dual band/dual polarization antennas.
The scope focuses on antenna parameters that are not the essential-requirements limits themselves. Those essential-requirements limits for Article 3.2 of the R&TTE Directive are given in EN 302 217-4-2, while test procedures and test conditions are covered by EN 301 126-3-1.
The document is organized into:
- Clause 1-2: scope and references
- Clause 3: definitions, symbols and abbreviations
- Clause 4: frequency bands
- Clause 5: classification of antennas
- Clause 6: electrical characteristics
- Annex A: normative class 1 radiation pattern envelopes
- Annex B: informative additional information
- Annex C: informative antenna gain and radiation pattern information
| Annex | What it covers |
|---|---|
| Annex A | Standardized Radiation Pattern Envelopes (RPE) for class 1 antennas in bands 3 GHz to 86 GHz |
| Annex B | Additional information on mechanical characteristics, connectors, return loss, inter-port isolation and labelling |
| Annex C | Antenna gain and radiation pattern information, including frequency-planning guidance |
What are the key requirements of SIST EN 302 217-4-1 V1.3.1:2009?
SIST EN 302 217-4-1 V1.3.1:2009 sets the framework for how antennas are grouped and which antenna parameters matter for system use. In practice, the document helps a reader decide which antenna class applies, which frequency range is relevant, and where to find the conformance limits used for declaration.
Frequency ranges and why they matter
Clause 4 divides the 1 GHz to 86 GHz range into eight sub-ranges. These ranges are the basis for the different technical commonalities used later in the classification templates and RPE figures.
For a reader, this means antenna data cannot be treated as one broad band. The applicable class template depends on the operating range.
Antenna classification by RPE and XPD
Clause 5 says antenna classification is based on Radiation Pattern Envelope (RPE) and Cross-Polar Discrimination (XPD). The document identifies four RPE classes and three XPD categories.
This matters because the antenna class affects network planning, interference risk and product comparison. A buyer or planner needs the class, not just the antenna name, to understand how directional the antenna is and how it will behave with co-polar and cross-polar signals.
Radiation Pattern Envelope classes
Clause 5.1 uses co-polar limit templates for actual RPE masks, shown in Figures 1 to 4 and summarized in Table 1. The templates define class 2, class 3 and class 4 limits across the different frequency ranges, and class 1 is defined as an actual RPE that exceeds the class 2 template.
In practice, this is the core classification tool for antenna directivity. When more than one standardized RPE falls into the same class template, a sub-class indicator such as A, B or C may be used to show which template is more demanding close to the intended direction.
Cross-Polar Discrimination categories
Clause 5.2 defines three XPD performance categories:
- XPD category 1 - standard cross-polar discrimination
- XPD category 2 - high cross-polar discrimination
- XPD category 3 - high cross-polar discrimination through an extended angular region
This matters for dual polarized systems and for techniques such as CCDP or ACAP, where polarization performance affects link performance and frequency reuse.
Electrical characteristics linked to conformance
Clause 6 states that co-polar and cross-polar RPEs, XPD and antenna gain are relevant electrical characteristics. For essential requirements under Article 3.2 of the R&TTE Directive, the actual limit values are given in EN 302 217-4-2.
For users, this means SIST EN 302 217-4-1 is the classification and system-dependent companion, while EN 302 217-4-2 carries the essential conformance limits. Annex C adds practical gain and pattern background for circular-symmetric antennas, and TR 102 243-1 gives representative values for gain and diameter to support compatibility and sharing analysis.
Practical mechanical and interface guidance
Annex B gives guidance on environmental operation, wind ratings, antenna stability, input connectors, return loss, inter-port isolation and labelling. Although informative, these points are important in procurement and installation because they affect whether the antenna fits the site, the feeder and the overall system design.
What terms does SIST EN 302 217-4-1 V1.3.1:2009 define?
SIST EN 302 217-4-1 V1.3.1:2009 relies on the definitions in EN 302 217-1, and several terms are central to reading the document.
- Fixed Radio Systems (FRS) - fixed wireless communication systems used for radio links between defined locations.
- Point-to-Point (PP) - a radio link between two endpoints, usually used for backhaul or fixed transmission.
- Radiation Pattern Envelope (RPE) - the limit mask that defines how much radiation is allowed away from the main beam.
- Cross-Polar Discrimination (XPD) - a measure of how well an antenna separates the wanted polarization from the orthogonal one.
- Digital Fixed Radio Systems (DFRS) - digital fixed radio systems mentioned in the guidance on essential requirements.
- Equivalent Isotropically Radiated Power (E.I.R.P.) - the apparent radiated power in a given direction, used in frequency planning.
- Voltage Standing Wave Ratio (VSWR) - a connector and feeder matching measure mentioned in Annex B as a typical antenna interface indicator.
Who uses SIST EN 302 217-4-1 V1.3.1:2009?
SIST EN 302 217-4-1 V1.3.1:2009 is used by antenna suppliers, radio equipment suppliers, network planners and purchasers working with point-to-point fixed radio systems. It is also used by engineers who need to choose antenna classes for frequency planning, interference assessment and link design.
In practice, these users apply it when they:
- classify antennas by RPE and XPD
- compare antennas for a planned link
- agree interface details such as connectors, return loss and inter-port isolation
- support conformance work with EN 302 217-4-2 and EN 301 126-3-1
- evaluate gain, beamwidth and main-lobe behavior for system planning
Which standards are used with SIST EN 302 217-4-1 V1.3.1:2009?
SIST EN 302 217-4-1 V1.3.1:2009 is used with several related documents that supply the limits, test methods and supporting definitions.
- Directive 1999/5/EC (R&TTE Directive) - the legal framework for the essential requirements referenced throughout the document
- EN 301 126-3-1 - definitions, general requirements and test procedures for point-to-point antennas
- EN 302 217-1 - common characteristics, definitions, symbols and abbreviations for the series
- EN 302 217-4-2 - the harmonized EN that gives the essential-requirements limits for antennas
- IEC 60154-1 and IEC 60154-2 - flange requirements for waveguide interfaces
- IEC 60169-1 - requirements and measuring methods for radio-frequency connectors
- TR 101 506 - guidance on terminology and applicability of essential requirements
- EN 302 217-2-1 and EN 302 217-2-2 - related system-dependent requirements for digital systems
- TR 102 243-1 - representative gain and antenna diameter values for compatibility and sharing studies
- ITU-R Recommendation F.699 - reference radiation patterns for coordination and interference assessment
What does the SIST EN 302 217-4-1 V1.3.1:2009 document contain?
SIST EN 302 217-4-1 V1.3.1:2009 contains the frequency-band breakdown, the antenna classification rules, the RPE template figures and the electrical characteristics that matter for point-to-point antennas. Annex A supplies standardized class 1 RPE figures for several frequency ranges, while Annex B and Annex C add practical guidance rather than normative limits.
The document is useful for design, procurement, compatibility checks and frequency planning because it ties antenna shape, polarization behavior and gain-related discussion to the system context. It also points readers to the companion standard that carries the essential conformance limits and to the test standard used for antenna verification.

4 Frequency bands
The present document defines the characteristics and requirements of antennas in the frequency range from 1 GHz to
86 GHz.
For technical commonalities that range is here divided into sub-ranges as follows:
Range 0: 1 GHz to 3 GHz;
Range 1: 3 GHz to 14 GHz;
Range 2: 14 GHz to 20 GHz;
Range 3: 20 GHz to 24 GHz;
Range 4: 24 GHz to 30 GHz;
Range 5: 30 GHz to 47 GHz;
Range 6: 47 GHz to 66 GHz;
Range 7: 66 GHz to 86 GHz.
5 Classification of antennas
Antenna classification presented in the present document is based on RPE and XPD parameters.
5.1 Templates for definition of Radiation Pattern Envelope
(RPE) classes
The RPE directional characteristic (co-polar and cross-polar) impacts the interference situation in the network planning
and a trade-off between a highly demanding RPE and the cost/size/weight of the antennas, compatible with the
constraints given by present and future networks is then advisable.
With respect to the Radiation Pattern Envelope (RPE), four classes (RPE classes 1 to 4) have been identified according
maximum co-polar limit templates for any actual RPE mask in significant range of off-axis azimuth angles. The
templates for subdivision in those classes are also depending on given frequency ranges of operation according to
figures 1 to 3 and table 1.
Figures 1 to 3 are intended only as templates for defining subdivision of antennas in directivity classes; actual
limits options for declaration of conformance to essential requirements under article 3.2 of the R&TTE
Directive [1] are defined only in EN 302 217-2-2 [i.2].
When more than one actual standardized RPE falls within the same class template, a sub-class indicative (A, B, C, etc.)
will be used according their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 3 report limit templates for any actual RPE mask of classes 2, 3 and 4 antennas; class 1
antennas are defined as those which actual RPE mask exceeds class 2 limit template.

4 Frequency bands
The present document defines the characteristics and requirements of antennas in the frequency range from 1 GHz to
86 GHz.
For technical commonalities that range is here divided into sub-ranges as follows:
Range 0: 1 GHz to 3 GHz;
Range 1: 3 GHz to 14 GHz;
Range 2: 14 GHz to 20 GHz;
Range 3: 20 GHz to 24 GHz;
Range 4: 24 GHz to 30 GHz;
Range 5: 30 GHz to 47 GHz;
Range 6: 47 GHz to 66 GHz;
Range 7: 66 GHz to 86 GHz.
5 Classification of antennas
Antenna classification presented in the present document is based on RPE and XPD parameters.
5.1 Templates for definition of Radiation Pattern Envelope
(RPE) classes
The RPE directional characteristic (co-polar and cross-polar) impacts the interference situation in the network planning
and a trade-off between a highly demanding RPE and the cost/size/weight of the antennas, compatible with the
constraints given by present and future networks is then advisable.
With respect to the Radiation Pattern Envelope (RPE), four classes (RPE classes 1 to 4) have been identified according
maximum co-polar limit templates for any actual RPE mask in significant range of off-axis azimuth angles. The
templates for subdivision in those classes are also depending on given frequency ranges of operation according to
figures 1 to 3 and table 1.
Figures 1 to 3 are intended only as templates for defining subdivision of antennas in directivity classes; actual
limits options for declaration of conformance to essential requirements under article 3.2 of the R&TTE
Directive [1] are defined only in EN 302 217-2-2 [i.2].
When more than one actual standardized RPE falls within the same class template, a sub-class indicative (A, B, C, etc.)
will be used according their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 3 report limit templates for any actual RPE mask of classes 2, 3 and 4 antennas; class 1
antennas are defined as those which actual RPE mask exceeds class 2 limit template.

5 Classification of antennas
Antenna classification presented in the present document is based on RPE and XPD parameters.
5.1 Templates for definition of Radiation Pattern Envelope
(RPE) classes
The RPE directional characteristic (co-polar and cross-polar) impacts the interference situation in the network planning
and a trade-off between a highly demanding RPE and the cost/size/weight of the antennas, compatible with the
constraints given by present and future networks is then advisable.
With respect to the Radiation Pattern Envelope (RPE), four classes (RPE classes 1 to 4) have been identified according
maximum co-polar limit templates for any actual RPE mask in significant range of off-axis azimuth angles. The
templates for subdivision in those classes are also depending on given frequency ranges of operation according to
figures 1 to 3 and table 1.
Figures 1 to 3 are intended only as templates for defining subdivision of antennas in directivity classes; actual
limits options for declaration of conformance to essential requirements under article 3.2 of the R&TTE
Directive [1] are defined only in EN 302 217-2-2 [i.2].
When more than one actual standardized RPE falls within the same class template, a sub-class indicative (A, B, C, etc.)
will be used according their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 3 report limit templates for any actual RPE mask of classes 2, 3 and 4 antennas; class 1
antennas are defined as those which actual RPE mask exceeds class 2 limit template.
