PHASED-ARRAYS OF PROBE-FED STACKED MICROSTRIP PATCHES

This paper presents calculated and measured results for infinite phase d arrays of probe-fed stacked rectangular and circular microstrip patc hes. A numerical model is described that is based on a rigorous Green' s function/Galerkin solution. In this solution, the connection of one or more vertical probe feeds to each patch is accurately modeled using a special attachment mode basis function, which is derived from the c orresponding cavity model solution. Numerical results for both linearl y and circularly polarized arrays are obtained. Measured results from a waveguide simulator are also presented and used to validate the nume rical model.
