IEEE 149-1977

This document comprises test procedures for the measurement of antenna properties. It is a comprehensive revision and extension of the previous test procedure ANSI/IEEE Std 149-1965 (Reaff 1971). Throughout this standard it is assumed that the antenna to be measured can be treated as a passive, linear, and reciprocal device. Therefore its radiation properties can be measured in either the transmitting or the receiving mode. Many of the test procedures described can, however, be adapted for use in the measurement of antenna systems containing circuit elements that may be active, nonlinear, or nonreciprocal. For these cases there is no simple relationship between the antenna system's transmitting and receiving properties. Therefore measurements shall be performed for the mode or modes in which the antenna system has been designed to be used.



New IEEE Standard - Inactive-Reserved. This standard is used throughout government, industry and academia in the area of antenna testing. It provides many of the procedures currently used by antenna test organization. However, the technology has passed the standard by in the areas and many areas and equipment are not included. This update will include these.
