Measurement of the Impulse Response of Communication Antennas

Abstract

A technique for measuring the transient response of uhf and vhf communication antennas is described. The procedure permits accurate determination of the impulse response of linear, time invariant antennas over the bandwidth of concern for high-altitude EMP. The experimental procedure is easy and inexpensive to implement and is suitable for laboratory and field testing. A key part of the experimental equipment is the transverse electromagnetic (TEM) horn antenna, which permits illumination of the test antenna with a single short pulse of energy. Special balanced configurations of the TEM horn have been developed to provide optimum radiation characteristics without the need for a conducting ground plane. A wire-grid model was developed for field testing and transportable applications. Measured transient responses of several antennas are presented. Data processing techniques for obtaining the impulse response from measured data are presented along with a comparison of predicted and measured response to a simulator.
