It is observed that some antennas can transmit a signal conforming to the applied voltage to the far field without any distortion in the time domain, whereas other antennas can receive a signal from the far field which will induce a current on the antenna conforming to the shape of the incident field.With a pair of transmit/receive antennas chosen from this class, one can construct a communication system that will transmit a time-domain wideband signal and receive it without any distortion of the pulse shape. In this article, we study the effects of the presence of obstacles along the path between the transmit and receive antennas, and we demonstrate that in some cases even when the signal is scattered by the obstacles, the shape of the received scattered pulse may not get distorted.
