摘要：
In this letter, circularly polarized meshed patch antenna has been investigated. A new technique is proposed to provide circular polarization for meshed patch antenna. Moreover, two mesh configurations have been studied, and their opto-radio-electrical performances have been compared to each other. It is shown that there is a conflict between optical transparency and bandwidth of the antennas. Additionally, the Proximity coupling technique has been modified to feed the meshed patch providing more optical transparency for the whole assembly. In the current study, two fabricated circularly polarized meshed patch antennas are presented, one with copper ground plane, another with solar cell ground plane. Measurement results show 2.79% and 3.27% axial-ratio bandwidth (3 dB) at center frequency of 2.43 GHz as well as 4.9 and 4.4 dBiC gain for meshed patch antennas with copper and solar cell ground plane, respectively.
