Ultra-Wideband Impulse Receiving Antenna Design and Evaluation

Impulse antennas are antennas that are intended to either transmit or receive very short pulses of electromagnetic energy. As is well known, short pulses have extremely wide bandwidths; hence, impulse antennas by their very nature must be wideband. However, in order to maintain signal fidelity, the bandwidth of an impulse antenna cannot be defined in the conventional manner. Unlike wideband continuous wave (CW) antennas, it is very important that the impulse antenna not introduce significant phase distortion into the signal.
