Abstract
Antennas used to radiate short pulses often require different design rules than those that are used to radiate essentially time-harmonic signals. If one considers only the performance in the time-domain, i.e., time varying waveforms, then the following are reasonable criteria for the performance of the antenna: (i) The radiated pulse should be a faithful reproduction of the excitation; i.e., there should be little pulse distortion on radiation, (ii) The reflected signal at the input of the antenna should be small. For practical systems, the peak amplitude of the reflected signal typically is required to be 40 dB below that of the incident signal, (iii) The amplitude of the radiated signal in the desired direction should be as large as possible.
