Alternative antenna measuring methods with use of impulse UWB radar

Abstract

This paper presents alternative methods of measuring the electric properties of antennas. In this case, the UWB impulse radar system is used. Also, the paper describes a relatively low cost measuring system, its calibration, verification and calculation methods of the required parameters - return loss and radiation pattern. All experimental results obtained by UWB radar are compared with the results obtained by measurements in an anechoic chamber. Experimental results of the measurements using UWB impulse radar system show good agreement with the simulated performance and with the measurements in the anechoic chamber.
