Summary:
A circularly-polarized high-gain green antenna using a solar panel as a frequency selective surface for Fabry-Perot cavity is proposed. First, the transmission and reflection coefficients of a square solar cell were analyzed for predicting the operating frequency of a green antenna with circular polarization and high gain operation. Next, the green antenna was constructed, and it consists of a square solar panel with 6 × 6 solar cells and a circularly polarized patch antenna backed with a metal ground plate. The achieved impedance bandwidth of the proposed green antenna is 154 MHz (2.928 ~ 3.082 GHz), and the CP bandwidth is 76 MHz (2.907 ~ 2.983 GHz). The antenna gain within the CP bandwidth is 13.0 ~ 13.9 dBic.
