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. The present document is applicable to fixed radio equipment with integral or dedicated antennas, and to stand-alone antennas. In the latter case the present document may be used to provide guidance as to the information to be supplied by a manufacturer as required by article 10 paragraph 8 of Directive 2014/53/EU [i.2]. 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. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

ETSI ETSI EN 302 217-4 V2.1.1 (2017-05) 7 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 state, for each antenna type, the frequency band of operation and antenna gain at least 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. 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 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 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 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.
