L-probe proximity-fed short-circuited patch antennas

Abstract

Experimental results for L-probe proximity-fed short-circuited quarter-wavelength patch antennas are presented. Using a foam layer of thickness ~0.1λ0 as a supported substrate, an impedance bandwidth of 39% and a gain of > 7.0 dBi have been obtained. The far field patterns are stable across the passband.
