Efficient magnetic current model for analysis of LTCC electrically small antennas at Ka band

An efficient magnetic current model for the analysis of low temperature cofired ceramics (LTCC) small aperture coupled patch antennas at high frequency is presented. The approach is based on the method of equivalence magnetic current and its closed-form multilayer Green's function in the spatial domain coupled with the method of moments (MoM). Numerical results of the Green's function and return loss of the LTCC small antennas at Ka band are analyzed.
