A comparison of time- and frequency-domain measurement techniques in antenna theory

Although the impulse response and complex spectral frequency response are mathematically equivalent, their measurement for wide-band antennas and probes is quite different in the equipment required, calibration and experimental procedure, and in the character of experimental errors. The subject of this communication is an automated facility for measurement of both time- and frequency-domain antenna response data, and a comparison of the results obtained by the two techniques.
