Abstract

Most part of the radiation theory has been developed in the frequency domain. There have been different researchers who worked on the antenna theory in the time domain in the past as well. The main question still is: how an antenna radiates? The radiation mechanism, near-field, and energy flow have been studied in the frequency domain for single frequency cases. One needs to study all the above for a wideband signal in the time domain. In the other hand, we need to understand the transient state of an antenna in the near and far zone. We also want to demonstrate the reactive energy density and the radiation power flow for a short pulse in the near zone as well.
