Abstract

Wideband T-probe proximity-fed regular circular and compact semicircular patch antennas are proposed in this paper. For the regular circular patch antenna, using a foam layer of thickness ∼0.13λ0 as a supported substrate, an impedance bandwidth of 35% and a gain of over 8.0 dBi have been obtained. For the compact semicircular patch antenna, an impedance bandwidth of 56% anti a gain of over 5.4 dBi are achieved with the same substrate thickness. The far-field patterns are stable across the passband. Experimental and computed results based on the finite-difference time-domain method are provided.
