Patch antennas on inhomogeneous substrates
(2002) In Technical Report LUTEDX/(TEAT-7105)/1-14/(2002)- 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.

The radiation patterns are computed with an FDTD program. However, only
small influences on the radiation patterns are observed. (Less)
