Abstract :
The parameter energy link loss between the source of the transmitter and the load of the receiver is used to evaluate the performance of a ultrawideband (UWB) radio system. The rigorous calculation of the link loss in a UWB system is a complicated task. However, for the special cases of two similar small antennas (dipoles and loops) a simple approximate analytical estimation of this parameter can be obtained. These expressions are derived assuming that the antennas are excited by Gauss-Hermite pulses (GHP). For the first three modes (n = 0, 1, 2) simple formulas for the optimum load resistance are derived.
