Abstract :
The authors present a theoretical analysis of the receiving characteristics of a microstrip patch array of infinite extent consisting of circular patches with offset feedpins. Galerkin´s method solutions to the integral equation of both the scattering and transmitting cases have been implemented on a Cray X-MP/48 supercomputer. The scattering case is solved for the electric field polarization both parallel and perpendicular to the plane of incidence. The current and the patch current K/sub 1/ are obtained for both of these cases. The transmission case is then solved and the input impedance and K/sub 2/ are obtained. Numerical results are obtained for input impedance, feed pin current, and power received over the frequency range 3 to 10 GHz, for both cases of electric field polarization.<>
