摘要

A broadband receiving antenna was implemented using a resistively-loaded thin-film V-monopole and a 500-Ω oscilloscope probe. The pulse-receiving performance of the antenna was evaluated using a time-domain antenna range. The antenna was also tested in a TEM cell both in time and frequency domains. The antenna is capable of receiving a 520-ps approximately Gaussian pulse, incident within 45° from the boresite direction, with good fidelity. The frequency-domain receiving transfer function (or the effective height) of the antenna is within -57±3 dB metres in the 22 MHz-1.1 GHz frequency range.
