The coupling characteristics between spherical concentric annular-ring and circular microstrip antennas are studied using full-wave analysis. Both the annular-ring and circular patches are fed by a coaxial probe. Such kind of coupling problem is treated as a two-port network and the coupling coefficient can be obtained from the scattering matrix. The numerical results of E-plane and H-plane coupling coefficients are presented and discussed.
