An analysis is presented of an infinite array of printed patches on a grounded anisotropic-dielectric slab. The array is considered as both a transmitter fed by idealized probes and as a scatterer of plane waves. For the transmitter case, the input reflection coefficient versus incident angle is computed for various loads and substrates. The theory in both cases is confirmed by comparing its limit to isotropic cases with previous analyses. The inputs to the analysis are the substrate parameters, the array grid geometry, the patch dimensions including probe position, and the probe load impedance, which is assumed conjugate matched at broadside for the transmit case.
