IEEE Std 149™-1979 R2008 Revision of IEEE Std 149-1965 IEEE Standard Test Procedures for Antennas Sponsor Antenna Standards Committee Reaffirmed December 10, 2008 Approved December 15, 1977 IEEE-SA Standards Board Approved October 9, 2003 American National Standards Institute ii Foreword This Foreword is not a part of ANSI/IEEE Std 149-1979, IEEE Standard Test Procedures for Antennas. This document is a major revision of IEEE Std 149-1965 which it supersedes. It represents the second revision of the standard since the original issuance in 1948 of 48IRE2S2, Standards on Antennass of Testing. Practically every topic contained in the previous standard has been expanded to reect the great changes that have taken place, since 1965, in metrology and instrumentation technology as applied to antenna measurements. This document contains sections on the design, uation, and operation of antenna ranges, electromagnetic radiation hazards, and environmental factors which did not appear in the preceding standard. The section on the determination of scattering cross-section, which appeared previously, has been omitted since it will appear as a separate standard at a later date. Suggestions for the improvement of this standard will be welcome. They should be sent to Secretary IEEE Standards Board The Institute of Electrical and Electronics Engineers, Inc 345 East 47th Street New York, NY 10017 This standard was prepared by the Subcommittee 2.11 on s of Testing Antennas of the IEEE Antenna Standards Committee.
