Abstract

Antenna structures capable of supporting (essentially) transverse electromagnetic (TEM) spherical waves are characterised by their frequency independence over a wide band width, making them ideal candidates for transient field radiation. In particular the triangular plate configuration of the TEM horn is of interest for a variety of directive wide-band applications including ultrawideband radar pulse transmission [1] and feeds for paraboloidal reflector antenna systems [2]. The basic design is founded upon idealised, infinitely long, conical antennas which have been studied by several authors including [3] and [4]. However in producing practical antennas which optimise the desired characteristics of the radiated pulse train, several modifications are required to accommodate the presence of high strength dielectric media preventing breakdown at high voltage and high pulse repetition frequency operation. In particular the dielectric/air boundary must be shaped to minimise reflection of energy at the interface.
