Actual antenna radiation pattern measurements in reverberation chamber

A reverberation chamber (RC) is an electrically large, highly conductive resonant enclosure used as test facility for radiated emissions and immunity measurements on electronic devices. In current literature, it is commonly stated that antenna radiation patterns cannot be measured, if needed, in RC. On the contrary, in this contribution, a novel technique that allows for the first time to perform actual antenna radiation pattern measurements in RC is presented. In order to demonstrate its validity, the radiation pattern for both E- and H- planes of a horn antenna has been measured in an RC at 10 GHz, in X band, and compared to the ones obtained in anechoic chamber, being the results in good agreement.
