A multilayer patch antenna with polarization multiplex is presented. The key element is a resonant feed ring which provides both circular polarizations and ensures adequate port separation. The arrangement features the compactness required for highly integrated antenna arrays. The design procedure is outlined. Measurements compare well with simulated S-parameters, gain, axial ratio, and far-field patterns. Broadband performance is demonstrated.
