Input Impedance and Radiation Pattern of a Rectangular Microstrip Antenna on an Anisotropy Substrate with Air Gap and Superstrate

초록

The input impedance and radiation pattern of a rectangular microstrip patch antenna on an anisotropy substrate with superstrate and air gap between the substrate layer and ground plane were studied using a rigorous Green's function formulation in the spectral domain and Galerkin's moment method calculation. Results show that input impedances and radiation patterns with varying air gap, permittivity of the superstrate and suvstrate, and superstrate theckness can be determined and analyzed.
