A Novel Reduced-Size Edge-Shorted Patch Antenna for UHF Band Applications

In this letter, we present a novel printed patch antenna design in the UHF band. This antenna consists of an edge-shorted patch, parasitic element, and metal reflector, making it easy to combine directional, high-gain, low cross-polarization and wide bandwidth. Reduction in patch size of up to 50% with respect to a traditional rectangular patch operating at the same frequency is obtained. The experimental results of the constructed prototype are presented.
