Broadband Pulsed Generator Based on H-Waveguide

Abstract

Generation of broadband pulses with complex waveform and spectrum is of interest for numerous applications. These pulses can be formed by high-power generators with spectral bandwidths (delta omega) / (omega roughly 0.5). Unlike ultra wideband (UWB) signal generators, broadband generators generate higher spectral power densities and have available effective antennas for transmission and receipt of these signals. The design of this generator was first described in [1] and is based on the direct driving of H-waveguides by gas-filled spark gaps. In this paper, the design of the dual spark-gap and of a mirror antenna with a customized broadband feed structure is presented. The dual spark-gap design includes a correcting capacitor. The designed shape of the mirror antenna provides high directivity of the transmitted radiation. In addition, the results of numerical simulations and experimental studies, targeting an increase in the operational efficiency and the radiated power levels of the generators, as well as the generation of radiation with the required spectra and waveforms, are presented.
