1 Scope The present document details standardized procedures for conformance testing of antennas for point-to-point radio relay systems [1] in order to achieve the approval by the Type Approval Authority. The procedure for dealing with established products are outside the scope of the present document. Standardized procedures are required in order to fulfil CEPT/ERC/DEC(97)10 [2] on the mutual recognition, within CEPT, of conformance test of antennas carried out in individual CEPT countries. The present document is intended to be applied in conjunction with the individual antenna standards and will enable commonality in the presentation of test results, irrespective of the Suppliers/accredited laboratory carrying out the test. NOTE: The Directive by the EEC [97-149 (COD)] and parallel work within CEPT ERC on mutual recognition, proposes that type approval against essential requirements can be carried out at manufacturers or third party premises. The level of accreditation required needs to be clarified by CEPT. The conformance tests described in the present document are related to antenna specific parameters required directly by the relevant antenna standards. Integrated antennas which cannot be separated from the equipment are not covered by the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

In this context approval implies that the IUT has met the essential requirements of the standard against which it has been tested. Complementary Requirements (CR): all those requirements not part of the essential requirements are complementary requirements. conformance testing: process to verify to what extent the IUT conforms to the standard essential requirements: basic set of parameters and functions which are necessary to meet any regulatory obligations imposed for radio frequency co-ordination Implementation Under Test (IUT): representative sample of the equipment for Conformance Testing Optional Requirements (OR): used in a standard with two different meanings: 1) optional in the sense that the parameter or function itself is mandatory but there is more than one possible value or configuration which may be chosen (e.g. class of Antenna RPE, frequency band(s), etc.). Once an option is selected it becomes mandatory; 2) optional in the sense that the feature is not mandatory (e.g. antenna input connector etc.). However, once such an option has been implemented it becomes mandatory that it conforms to the requirements of the present document. supplier: organization requesting the approval Supplier's Declaration (SD): procedure by which a supplier gives written assurance that a parameter or function conforms to the present document type approval authority: national Regulatory/Licensing Authority 3.2 Symbol For the purposes of the present document, the following symbol applies: dB decibel SIST EN 301 126-3-1 V1.1.2:2003

This declaration will also guarantee that the essential requirements shall be met for the environmental conditions given in clauses 5.1.5 and 5.1.6. NOTE 2: Alternative test methods may be agreed prior to testing. NOTE 3: SD is intended for proper selection among provided options or for information necessary to carry out the test.
Clear distinction is made between "Essential Requirements (ER)" which require "Approval Testing" for regulatory purpose and "Complementary Requirements (CR) or Optional Requirements (OR)" which fulfil the "Conformance Testing" against the relevant standards. The Type Approval Authority shall require the Supplier's Declaration which encompasses the test report demonstrating essential requirements (radiation pattern, antenna cross polar discrimination and gain), accompanied by evidence of accreditation to an internationally recognized Quality Standard, at least ISO 9001 [6]. The supplier shall be considered legally responsible for any statement in the declaration. Annex A contains the Supplier's Declaration template for all the parameters in table 1. Annex B contains the Test Report template for the essential requirements listed in table 1. SIST EN 301 126-3-1 V1.1.2:2003



ETSI ETSI EN 301 126-3-1 V1.1.2 (2002-12) 10 Test Methods shall be adopted in accordance with IEC 60835-2-2 [7], although suitable test methods may be agreed between the Supplier and the type approval authority, prior to testing. A description of the test method is to be included in the test report. 4.2 Implementation under test (IUT) The IUT presented for Type approval shall be a representative production model. Testing shall be conducted at point D (D') in figure 1. An appropriate adapter shall be used if required to connect the antenna at point D (D') to the test equipment and the effects of the adapter upon the test results shall be taken into account and declared. The configuration used during the test shall be provided in the test report clearly indicating point D (D').

Where necessary, for better understanding of the application of test methods, reference is made to IEC 60835-2-2 [7] (Test methods). Alternative test methods, among them compact antenna test ranges or near-field scan, may be agreed between the Supplier and the Type Approval Authority prior to testing. 6.1 Radiation Pattern Envelope (RPE) 6.1.1 Objective To verify that the antenna radiation pattern, for the declared class and frequency range, is contained within the limits of the stated RPE from the relevant standard.

The antenna shall be measured as a minimum at the lowest, middle and highest frequency of (each of) the declared frequency band(s). The cross-polar radiation patterns shall be recorded after an alignment procedure based on the minimization of the cross-polar level in the frequency band(s) of the antenna. This setting shall be maintained for all the cross-polar measurements at all frequencies. 6.1.4 Test procedure example (alternative test procedures could be used) a) All adjustments have to be made at middle frequency. b) Adjust the polarization of the IUT to be parallel or perpendicular to the azimuth plane containing the transmission axis. c) Align the azimuth and elevation of the transmitting antenna and the IUT for maximum co-polar signal. d) Change the polarization of the transmitting antenna to cross-polar. e) Adjust the polarization of the transmitting antenna to the minimum cross-polar level. f) Change the polarization of the transmitting antenna back to co-polar. g) This alignment should be maintained for all measurements. (In the case of a single polarized antenna the alignment has to be repeated for the other polarization). h) Perform co-polar and cross-polar measurements at lowest, middle
