摘要：

This contribution presents a novel measurement approach to characterize the pulse reception behavior of UWB antennas using a GTEM cell. By evaluating the respective reception properties the transmit characteristics are calculated via the Lorentz's reciprocity theorem. The cell is excited at its feeding port by an UWB pulse covering a frequency range up to 10 GHz. The antenna is placed inside the testing volume. Due to the fact, that pure TEM propagation predominates within a distinct time interval, electrical small antennas can be characterized with a negligible influence of either field distortion or pulse dispersion effects. Hence, the time-gated receive signal of the antenna can be used to compute the impulse response directly via deconvolution of the incident electric field and the voltage at the antenna's feeding port.
