On the computation of the input impedance for probe-fed chirostrip rectangular patch antennas

This paper presents a full-wave analysis method for planar arbitrarily shaped chirostrip structures. Working in the Fourier domain, dyadic spectral Green functions in compact and closed-form are derived. The Galerkin procedure is used to solve numerically a coupled integral equation for the surface electric current density. Effects of the chiral admittance on the resonant frequency and input impedance of probe-fed chirostrip rectangular patch antennas are discussed. Results for linearly and circularly polarised radiators are presented.
