Application of IEEE Std 149–2021 ™: International Antenna Measurement Campaign

The IEEE Std 149–2021 ™ recommended practice for antenna measurements was recently revised by the IEEE Antennas and Propagation Standards Committee (APS/SC), sponsored by the IEEE Antennas and Propagation Society (AP-S). The document represents a major revision of IEEE Std 149-1977™. It describes the procedure for the measurement of the transmitting and receiving properties of an antenna that is assumed to be a passive, linear, and reciprocal device. Among different topics addressed, it provides guidance about the antenna range design and evaluation. To complement this document, an international antenna measurement campaign was launched in an aim to provide an example of measurement that may be expected when applying this standard. A 5G New Radio (NR) ultrawide band (UWB) antenna was selected for this measurement campaign.
