IEEE Recommended Practice for

Antenna Measurements

Developed by the

Antennas and Propagation Standards Committee

of the

IEEE Antennas and Propagation Society

Approved 23 September 2021

IEEE SA Standards Board

Abstract: The recommended practices for the measurement of antenna transmitting and

receiving properties are presented. Throughout this standard it is assumed that the antenna to be

measured can be treated as a passive, linear, and reciprocal device. A fundamental property of

any antenna is its radiation pattern. The measurement of radiation patterns in an antenna test

facility is discussed. The design of antenna test facilities is described along with instrumentation

requirements for the proper operation of the antenna facility, directions for the evaluation of an

(existing) range, and the operation of ranges is discussed. References are provided that are

illustrative of measurement techniques and in which details may be found.
