Generalized Green´s function analysis of infinite arrays of microstrip antennas with various configurations

A flexible method employing a generalized spectral form of the periodic Green´s function, has been developed to model infinite-array microstrip structures of various configurations. The method is able to handle structures with dielectric substrates which may be finite in extent, or infinite in one or both dimensions. Efficient implementation of the method allows well-converged results to be obtained quite quickly using desktop computers. Research is being done to extend the method to include feedlines and other standard features, and to employ the models to further study finite substrates effects on such microstrip arrays.
