Abstract

In this paper, a cross-coax fed low-profile short-circuited suspended patch antenna combined with a polycrystalline silicon (poly-Si) solar cell operating as a radiating patch element is proposed for self-powered 2.4 GHz band WLAN and 2.3/2.5 GHz band WiMAX networks. The fabricated multifunctional solar patch antenna has a measured wide impedance bandwidth of 840 MHz, 35%, and offers a broadband gain of 7.71 dBi. It operates with a measured solar efficiency of 13.9%, generating a DC power output of 225 mW.
