Abstract

In this paper, we search for a suitable way of characterizing antennas in a wide band of frequencies. First, a canonical antenna is characterized by conventional parameters in frequency domain (directivity pattern, gain, input impedance) on each separate harmonics, and their mean-value counterparts are formulated and discussed. Second, the analysis is performed in the time domain, and following the frequency domain characterization, time-domain parameters are formulated. The correspondence between frequency-domain parameters and time-domain ones is shown using Parseval’s theorem. Conclusions are illustrated by numerical examples.
A novel formulation of time-domain antenna parameters and using Parseval’s theorem to show the correspondence between mean-value time-domain parameters and mean-value frequency-domain ones are the original contributions of this paper.
