Paper Abstract

This paper describes the performance of a broadband (0.3-10 GHz) cavity backed TEM horn with an exponential flare in two planes. The antenna pattern was measured using a pulsed source and found to have a 3 dB width of 50 deg. The two-way transfer function of a pair of these horns was determined using pulsed measurements. The two way gain of the horns was found to be 6 dB. Diffraction of the low frequency components of the radiated pulse was observed and the effects on waveform shape noted. In particular, we have observed that the back and side lobes of this antenna are dominated by the low frequency components, and the corresponding temporal waveform has a different shape than the waveform found in the main lobe.
