Abstract

A simple and compact design of solar-slot antenna for dual band 2.4/5.2GHz WLAN applications is proposed in this paper. The design makes use of amorphous silicon (a-Si:H) solar cells in polyimide substrate with embedded twin H-shaped slot structure to generate dual resonant frequencies. A T-shaped microstripline feed is used to excite the twin H-slot in the a-Si:H solar cell. The measured impedance bandwidth of the proposed solar antenna are 6.7% (165MHz) centred at 2.465GHz and 4.1% (212MHz) at 5.11GHz. The measured gain at 2.4 and 5.2 GHz are 3.5dBi and 3.1dBi respectively.
