Abstract :
This paper describes a version of the "Wheeler (1959) Cap method" modified for evaluating the efficiency of ultrawideband (UWB) antennas and discusses the application of this method to a Time Domain Corporation BroadSpec/spl trade/ Model 102 antenna. This antenna exhibits a radiation efficiency better than 90% from 1.5 GHz to above 6.0 GHz.
