Radiation efficiency and surface waves for patch antennas on inhomogeneous substrat
(2001) In Technical Report LUTEDX/(TEAT-7100)/1-48/(2001)- Abstract
- In this paper the surface wave characteristics, as well as the radiation efficiency
and the directivity of a patch antenna, with a given current distribution, located
on top of an inhomogeneous, isotropic substrate are calculated. The
substrate is infinite in the lateral directions and inhomogeneous with respect
to the height coordinate. The surface waves in the substrate are analyzed
using the propagator technique and residue calculus. The propagators and
the residues are found by solving two sets of systems of ordinary differential
equations (ODEs). Several dispersion curves of the surface waves for inhomogeneous
substrates are calculated. The radiation efficiency and... (More) - In this paper the surface wave characteristics, as well as the radiation efficiency

reflection dyadic of an inhomogeneous substrate are presented in a series of
