Abstract

Measured results of a dual-band shorted patch antenna excited by a combined L- and T-probe feed structure are presented. By using foam layers of thickness ∼0.12λ1 and ∼0.06λ2 to support the patches that are responsible for the lower and upper bands, impedance bandwidths (SWR ≤ 2) of 54.4% and 49.1% have been obtained, respectively. The far-field patterns are stable across the passband.
