Abstract
A 2 × 2.65 cm2 solar monopole antenna was designed and tested for both DC and RF performances within the 3¿10 GHz UWB frequency band. The amorphous silicon solar cell delivers up to 15 mW, suitable for autonomous low-power wireless transceivers. The radiation patterns and gain are comparable with a copper-only antenna for frequencies less than 5 GHz. Beyond 5 GHz, changes in the solar antenna radiation patterns are caused by the solar cell physical characteristics and DC output connections.
