Abstract :
This letter deals with using ultrawideband (UWB) Wheeler Cap (UWB WCap) and reverberation chamber (RC) to measure efficiencies of narrowband antennas. This first testbed designed for very broadband systems can also be accurate for narrowband antennas. The second one, first designed for electromagnetic compatibility (EMC) measurements, offers advantages to measure antenna efficiency. Results are given to assess uncertainty and accuracy of both measurement means.
