Why Every Member of the AP-S Should Own a Copy of the Antenna Measurement Standard IEEE Standard 149 [Stand on Standards]

The revised version of IEEE Standard 149 is finally available as IEEE Standard 149-2021, approved by the IEEE Standards Association Standards Board (SASB) in September 2021 and effectively published in February 2022. This is the first in-depth revision of the standard since 1979. Rewritten as a recommended practice, the standard is an essential desk reference for anyone involved in antenna measurements. While most instructions on antenna engineering are centered on the designs, types, and numerical methods applied to antennas, the standard focuses on the art of measuring antennas and understanding the best approach for measuring different parameters of antennas. With almost 200 bibliographical references, the standard provides guidance on the methods and approaches to measure realistic implementations of antennas or points the reader to relevant sources of information. No antenna engineer is completely prepared without an understanding of the proper approach to perform antenna measurements and how to estimate the uncertainty of an antenna measurement.
