Abstract :
This paper deals with using Reverberation Chamber to obtain antenna radiation efficiency. Reverberation Chambers methods which has for many years been used for EMC (Electromagnetic Compatibility) measurements, can be also used with great advantage for antenna measurements since it simulates effectively a uniform multi-path propagation environment. This paper describes how a Reverberation Chamber can be used to measure the ultra-wideband (UWB) antenna efficiency with very short time. The procedure based on time domain is described and some experimental results are given and compared to the Wheeler Cap method extended by Schantz to UWB antennas.
