High Gain Fabry-Perot Cavity Antenna Using Single Layered Partially Reflective Surface

This manuscript proposes high-gain Fabry-Perot cavity (FPC) antenna. The antenna incorporates a radiating patch and PRS layer mounted above the antenna layer. This PRS unit cell adopts uniform phase distribution with reflectivity of 0.9 and -174.26° reflection phase. This FPC antenna shows -10 dB impedance bandwidth from 9.7 GHz – 10.3 GHz. The single-layered PRS enhances the antenna gain, which attains 15.97 dBi peak gain at 10 GHz in the broadside direction. The proposed structure has cross-polarization well below 20 dB. The FPC antenna is fabricated and simulated performance is validated with measurement.
