Abstract

An analysis is presented of the radiation properties of infinite phased arrays of one- or two-probe-fed circular microstrip patches, using a rigorous Green's-function/moment-method approach. Two ways of treating the connection of a vertical feed probe to the patch are considered: an idealized probe feed model, which is useful for antennas printed on thin substrates or to predict general performance trends, and a more rigorous treatment that overcomes the deficiencies of the simpler model. This rigorous treatment seems to have some advantages over other published analyses, including applicability to a wide range of printed radiator problems, but requires a huge increase in the amount of computer time required for the calculation. Comparisons of both feed models with measured data from waveguide simulators are used to validate the theory for both one- and two-probe-fed elements.
