Matlab-based simulation of a slot antenna for pulse radiation

Abstract

A numerical study, based on the frequency-domain method of moments (MoM), is made of wideband properties of a slot linearly-polarized antenna, patented by Time Domain Inc. The antenna-to-antenna transfer function is evaluated over the band 12.5 MHz to 6.25 GHz. Predictions are made for the received voltage at different durations of the input voltage pulse. It is stated that the investigated antenna type is best suited for 1 ns wide pulses. When the pulse duration is smaller or greater than this value, the antenna performance declines.
