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)

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

appendices. (Less)
