Abstract :
A frequency-varying patch antenna design with a loaded capacitor is presented. Unlike traditional patch size reduction schemes, this capacitor-loaded scheme does not significantly affect the radiated power efficiency of the antenna. In some cases, the maximum radiated power can even be improved
