Experimental results for an L ‐probe‐fed shorted triangular patch antenna are presented. Using a foam layer of thickness ∼0.13λ 0 as a supported substrate, an impedance bandwidth of 61% (SWR≤2) and a gain of over 4.0 dBi in the bandwidth have been obtained. The far‐field patterns are stable across the passband.
