An extended variational formulation to study cavity-backed microstrip patch antennas with chiral materials is presented. A finite-element boundary integral numerical approach is applied to satisfy the stationary condition associated with the variational formulation and some features of chiral media for patch antenna applications are investigated. Specifically, an appreciable reduction of the antenna dimensions with respect to the isotropic case and an undesirable increase in the cross-polarization levels are observed.

Abstract

A finite-element boundary integral numerical approach is applied to satisfy the stationary condition associated with the variational formulation and some features of chiral media for patch antenna applications are investigated. Specifically, an appreciable reduction of the antenna dimensions with respect to the isotropic case and an undesirable increase in the cross-polarization levels are observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
