Abstract

The effective aperture of the antenna is determined using measured backscattering data. An oscillator with a known port impedance is connected to the antenna under test to modulate the backscattered radiation. The measurement is based on measuring the signal in the modulation sidebands. Using a simple circuit model for the antenna-oscillator system, the antenna effective aperture, bandwidth and radiation pattern can be determined. In this paper, theory for antenna aperture measurement is developed, and measurements with error considerations of an antenna with a highly reactive port impedance at the application frequency are presented. The results are compared to a traditional transmission measurement results.
