“…10. In [7] and [8] the GTEM cell was introduced as a linear time invariant (LTI) system, which can completely be characterized by its impulse response vector h GTEM (t). As has been stated in Section III., also the antenna can be described as a LTIsystem with an impulse response h AUT rx (t).…”

“…On the one hand, as shown in [7], the cell provides a well defined linearly polarized TEM test field over a wide frequency range, on the other hand the transient wave propagation behavior in an empty cell can be described by a linear time invariant (LTI) system [8]. In a first step only electrically small antennas under test (AUT) are considered for this approach.…”

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.
