A rigorous full‐wave analysis of rectangular microstrip‐patch resonators over ground planes with rectangular apertures is presented. The rectangular patches, as well as the ground planes containing the rectangular apertures, are embedded in a multilayered substrate containing isotropic and/or uniaxial anisotropic materials. Using a matrix representation of each layer, the dyadic Green's functions of the problem are efficiently determined by the (TM, TE) representation. The validity of the solution is tested by comparing the computed results with the experimental data. Numerical results show that the rectangular apertures significantly affect the resonant frequencies of the rectangular microstrip patches. © 2004 Wiley Periodicals, Inc.
