An analysis of infinite arrays of rectangular microstrip patches with each element fed by one or two coaxial probes is presented. The probe self-impedance and the rapidly varying patch current near the feed connection point are rigorously included in the analysis. Two-probe-fed patches are analyzed for both reduced cross-polarization and circular-polarization applications, and the effect of probe-to-probe coupling in the unit cell is determined. The theory generates results in excellent agreement with waveguide simulator measurements. Similar solutions can be developed for other types of patch antennas and arrays.
