1 Scope
The present document defines the characteristics and requirements of antennas for point-to-point radio equipment
operating in the frequency range from 1 GHz to 174,8 GHz falling within the scope (see note) of ETSI
EN 302 217-2 [i.2].
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 71 GHz;
Range 7: 71 GHz to 86 GHz;
Range 8: 92 GHz to 114,25 GHz;
Range 9: 130 GHz to 174,8 GHz.
The present document is applicable to fixed radio equipment with integral (see note) or dedicated antennas.
NOTE: For information, ETSI EN 302 217-2 [i.2] includes in its scope only the use of detachable integral
antennas; undetachable integral antennas are not considered due to the present lack of radiated test
procedures for the radio equipment parameters.
The present document also applies to stand-alone antennas, placed separately on the market. In this case the present
document is to be used by radio equipment manufacturers to provide guidance as to the information for the user, as
required by article 10 paragraph 8 of Directive 2014/53/EU [i.1], regarding the antenna characteristics required so as the
radio equipment, supplied without antenna, can operate as intended in its technical documentation.
The present document is applicable to fixed beam antennas, as well as to "self-alignment tracking" antenna, with limited
tracking range, so that all requirements in the present document are respected throughout the tracking angle indicated in
the technical documentation.
The main body of the present document specifies the characteristics that define the various antenna classes, whilst the
annexes provide additional information that is useful to both antenna manufacturers and user/installers.

4 Technical requirements specifications
4.1 Introduction
The electrical characteristics are given as function of specific classification of the antennas according to the principles
referred to in clause 4.2.
The antenna manufacturer shall indicate (e.g. in the technical documentation or other public documentation), for each
antenna type, the operating frequency band, the antenna nominal gain and its maximum deviation over the operating
frequency band (alternatively, at least the gain at the frequency band edges and at mid-band).
An antenna, which employs a radome, shall meet the requirements of the present document with the radome in place.
Self-alignment tracking antennas, shall meet all requirements in the present document throughout their tracking angle
indicated in the technical documentation.
The antenna system shall radiate a linear (single or dual) polarized wave.
4.2 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
to the "limit templates"; a "limit template" is intended as the maximum co-polar gain that any actual RPE mask of that
class (referred in clauses 4.4.2 to 4.4.11) should not exceed, in the significant range of off-axis azimuth angles, for
being considered within a class. The templates for subdivision in those classes are also depending on given frequency
ranges of operation according to figures 1 to 4 and table 1.
When more than one actual standardized RPE falls within the same class template, a sub-class indicative (A, B, C, etc.)
shall be used according to their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 4 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.

1 Scope
The present document defines the characteristics and requirements of antennas for point-to-point radio equipment
operating in the frequency range from 1 GHz to 174,8 GHz falling within the scope (see note) of ETSI
EN 302 217-2 [i.2].
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 71 GHz;
Range 7: 71 GHz to 86 GHz;
Range 8: 92 GHz to 114,25 GHz;
Range 9: 130 GHz to 174,8 GHz.
The present document is applicable to fixed radio equipment with integral (see note) or dedicated antennas.
NOTE: For information, ETSI EN 302 217-2 [i.2] includes in its scope only the use of detachable integral
antennas; undetachable integral antennas are not considered due to the present lack of radiated test
procedures for the radio equipment parameters.
The present document also applies to stand-alone antennas, placed separately on the market. In this case the present
document is to be used by radio equipment manufacturers to provide guidance as to the information for the user, as
required by article 10 paragraph 8 of Directive 2014/53/EU [i.1], regarding the antenna characteristics required so as the
radio equipment, supplied without antenna, can operate as intended in its technical documentation.
The present document is applicable to fixed beam antennas, as well as to "self-alignment tracking" antenna, with limited
tracking range, so that all requirements in the present document are respected throughout the tracking angle indicated in
the technical documentation.
The main body of the present document specifies the characteristics that define the various antenna classes, whilst the
annexes provide additional information that is useful to both antenna manufacturers and user/installers.

4 Technical requirements specifications
4.1 Introduction
The electrical characteristics are given as function of specific classification of the antennas according to the principles
referred to in clause 4.2.
The antenna manufacturer shall indicate (e.g. in the technical documentation or other public documentation), for each
antenna type, the operating frequency band, the antenna nominal gain and its maximum deviation over the operating
frequency band (alternatively, at least the gain at the frequency band edges and at mid-band).
An antenna, which employs a radome, shall meet the requirements of the present document with the radome in place.
Self-alignment tracking antennas, shall meet all requirements in the present document throughout their tracking angle
indicated in the technical documentation.
The antenna system shall radiate a linear (single or dual) polarized wave.
4.2 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
to the "limit templates"; a "limit template" is intended as the maximum co-polar gain that any actual RPE mask of that
class (referred in clauses 4.4.2 to 4.4.11) should not exceed, in the significant range of off-axis azimuth angles, for
being considered within a class. The templates for subdivision in those classes are also depending on given frequency
ranges of operation according to figures 1 to 4 and table 1.
When more than one actual standardized RPE falls within the same class template, a sub-class indicative (A, B, C, etc.)
shall be used according to their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 4 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.

1 Scope
The present document defines the characteristics and requirements of antennas for point-to-point radio equipment
operating in the frequency range from 1 GHz to 174,8 GHz falling within the scope (see note) of ETSI
EN 302 217-2 [i.2].
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 71 GHz;
Range 7: 71 GHz to 86 GHz;
Range 8: 92 GHz to 114,25 GHz;
Range 9: 130 GHz to 174,8 GHz.
The present document is applicable to fixed radio equipment with integral (see note) or dedicated antennas.
NOTE: For information, ETSI EN 302 217-2 [i.2] includes in its scope only the use of detachable integral
antennas; undetachable integral antennas are not considered due to the present lack of radiated test
procedures for the radio equipment parameters.
The present document also applies to stand-alone antennas, placed separately on the market. In this case the present
document is to be used by radio equipment manufacturers to provide guidance as to the information for the user, as
required by article 10 paragraph 8 of Directive 2014/53/EU [i.1], regarding the antenna characteristics required so as the
radio equipment, supplied without antenna, can operate as intended in its technical documentation.
The present document is applicable to fixed beam antennas, as well as to "self-alignment tracking" antenna, with limited
tracking range, so that all requirements in the present document are respected throughout the tracking angle indicated in
the technical documentation.
The main body of the present document specifies the characteristics that define the various antenna classes, whilst the
annexes provide additional information that is useful to both antenna manufacturers and user/installers.

4 Technical requirements specifications
4.1 Introduction
The electrical characteristics are given as function of specific classification of the antennas according to the principles
referred to in clause 4.2.
The antenna manufacturer shall indicate (e.g. in the technical documentation or other public documentation), for each
antenna type, the operating frequency band, the antenna nominal gain and its maximum deviation over the operating
frequency band (alternatively, at least the gain at the frequency band edges and at mid-band).
An antenna, which employs a radome, shall meet the requirements of the present document with the radome in place.
Self-alignment tracking antennas, shall meet all requirements in the present document throughout their tracking angle
indicated in the technical documentation.
The antenna system shall radiate a linear (single or dual) polarized wave.
4.2 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
to the "limit templates"; a "limit template" is intended as the maximum co-polar gain that any actual RPE mask of that
class (referred in clauses 4.4.2 to 4.4.11) should not exceed, in the significant range of off-axis azimuth angles, for
being considered within a class. The templates for subdivision in those classes are also depending on given frequency
ranges of operation according to figures 1 to 4 and table 1.
When more than one actual standardized RPE falls within the same class template, a sub-class indicative (A, B, C, etc.)
shall be used according to their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 4 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.
