Abstract

Correction factors between test sites are conventionally based on the antenna pattern of a tuned 1/2 λ dipole. Actual devices show diverse antenna patterns and correlation between results obtained at different test sites fails. This is shown in this paper using an Open Area Test Site, a Semi-Anechoic Chamber, a Full Anechoic Chamber and a Reverberating Intrinsic Reverberation Chamber for emission measurements between 20 MHz and 1 GHz. Differences between the sites of more than 40 dB can be observed.
