Information that is useful in constructing test sites used to perform radiated emission measurements in the frequency range of 30 MHz to 18 GHz is provided. Final validity of a test site can only be determined by performing normalized site attenuation and/or site voltage standing-wave ratio measurements as described in ANSI C63.4.

This paper describes a method of measuring the free-space antenna factors of above 1 GHz EMC antennas in a fully anechoic room (FAR) which is validated by comparison with an open area test site (OATS).
Our aim in this research work is to propose a methodology on receiving antenna height scan in the fully anechoic room (FAR) to minimize uncertainty in obtaining maximum emission of equipments under test (EUT) that have multilobe radiation patterns at higher frequencies. An EUT with complex slots is measured. The radiation emission for five antenna heights from 1 m to 1.8 m with a 0.2 m increment are...
