A Pulse Antenna Suite for IEMI Testing

This article describes the development and testing of a suite of high-voltage pulse antennas for IEMI susceptibility testing. The antennas are designed to operate with pulses up to 33 kV from a common solid state double exponential pulse generator, and to be light enough to operate on a standard EMC test mast. A broadband (hyperband) antenna intended to transmit the full pulse spectrum and two resonant (mesoband) antennas to produce damped sinusoidal pulses are presented. The antennas were prototyped using full wave numerical modelling and tested in an anechoic chamber in the frequency domain and with a high voltage pulse generator.
