Wideband Microstrip Antenna Using Solar Cells

A wideband microstrip antenna using solar cells is reported for green mobile communication. Wideband performance of 55.2% has been achieved from 1.67 GHz to 2.94 GHz with a height of 0.068$\lambda_{0}$, where $\lambda_{0}$ is the wavelength of 2.3 GHz at free space. 12 solar cells are adopted for photovoltaic generation, the coverage of solar cells over the total area is more than 60%. The proposed low-profile solar cell antenna can provide a wideband performance and photovoltaic generation simultaneously.
