Patch antennas on inhomogeneous substrates

Abstract
Patch antennas on inhomogeneous substrates are analyzed with the stable

FEM-FDTD hybrid method [T. Rylander and A. Bondeson, “Stable FEMFDTD

hybrid method for Maxwell’s equations,” Comput. Phys. Comm.

125, 75 (2000)] and an analytic propagator technique. For inhomogeneous

substrates with a fixed homogenized value of the permittivity, our results conjecture

that a decrease of the permittivity in the vicinity of the patch increases

the bandwidth and the resonance frequency. Furthermore, we find that inhomogeneous

substrates with the permittivity only varying with the height in-

fluence the field pattern within the substrate, but not the radiation effciency.

small influences on the radiation patterns are observed. (Less)
