Experimental results for an L-probe-fed shorted semicircular patch antenna are presented. Using a foam layer thickness ∼ 0.12 λ0 as a supported substrate, an impedance bandwidth of 57% (SWR ≤ 2) and a gain of over 4.0 dBi in the majority of the wide bandwidth have been obtained. The far-field patterns are stable across the passband.
