A Novel Scheme for Solar Cell Receiving Microwave Energy

In this paper, an integrated scheme for receiving solar energy and microwave energy simultaneously is proposed, which realizes the isolation of solar energy and microwave energy with the help of the way of microwave antenna aperture coupling. To demonstrate this concept, a 5.8GHz integrated rectified antenna was designed, fabricated and tested, based on a
$\boldsymbol{20}\ \mathbf{mm} \times \boldsymbol{20}\ \mathbf{mm}$
solar cell in this paper. As a result, the maximum output power of 565 mW was obtained when the integrated device is exposed to an environment with a power density of 3 mW/mm

while maintaining the original performance of the solar cell.
