Abstract :
An antenna that is used at both the transmit and receive end of the same dispersionless communications link should have a time domain response that looks like a half-derivative on transmit, at least over the frequency range of interest. Time domain reciprocity then dictates that the antenna will compensate for this half-derivative when used as the receiver, producing a flat channel response in the frequency domain. The desired waveform is produced by a pulsed infinite line source. An antenna concept based on a partially focused transverse electromagnetic horn might be able to mimic this performance over a finite frequency range.
