Radiation and scattering from circular microstrip patches

Abstract

The feed model of J.T. Aberle and D.M. Pozar (1988) is used to determine the radiation and scattering properties of isolated probe-fed circular patches terminated in arbitrary load impedances. The rigorous probe feed modeling makes it possible to accurately include the antenna mode component of scattering. The calculated and measured reflection coefficients at the input of an isolated probe-fed circular patch are shown, and the agreement between theory and experiment is quite good. The calculated monostatic radar cross section of an isolated probe-fed circular patch is shown for three different load impedances (open, 50 Omega , and short).<>
