Abstract

In the future, EMC measurements above 1 GHz will become mandatory. Currently, most newly realised full-compliance EMC chambers are already specified up to 18 GHz. However, whereas existing standards clearly specify the requirements between 26 MHz and 1 GHz, the standards for the higher frequency range are still in draft form. To construct such chambers, broadband EMC absorbers are required that are effective from 26 MHz to over 18 GHz. The absorber design needs to properly combine both low and high frequency concepts. Measurement results up to 18 GHz are shown for state-of-the-art anechoic EMC chambers for 3, 5 and 10 m test distance
