Receiving characteristics of an infinite circular patch antenna array

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.<
