A SOLAR CELL STACKED SLOT-LOADED SUSPENDED MICROSTRIP PATCH ANTENNA WITH MULTIBAND RESONANCE CHARACTERISTICS FOR WLAN AND WiMAX SYSTEMS

In this paper, a novel self-complementary shaped multiple-L slot loaded suspended microstrip patch antenna stacked with a polycrystalline silicon (poly-Si) solar cell is presented for 2.4/5.2 GHz band WLAN and 2.5/3.3/5.8 GHz band WiMAX networks. While the proposed self-complementary shaped multiple-L slot loaded suspended patch enables the propagation of multiple TMmn modes to be present, the poly-Si solar cell works as an RF parasitic patch element in addition to its photovoltaic function. The proposed stacked solar antenna combination topology enables the radiating patch to be easily modified by slot-loading to achieve multiband resonance characteristics and the poly-Si solar cell to operate without being shaded by any RF components of the antenna ensuring an optimum solar operation performance.
