Abstract: A novel metamaterial inspired small array Fabry-Perot Resonator cavity antenna is designed over a wide-band dielectric resonator antenna to enhance gain and bandwidth operating at C-band applications. Further, the cavity resonator is modified with the application of 12 no. of RF p-i-n diodes between the upper layer of the posterior unit-cells to achieve the polarization reconfigurability (PR) keeping the bandwidth, gain and efficiency intact. The overall dimension of the proposed antenna is 0.8 λ × 0.8 λ × 0.56 λ. With the PR architecture, the antenna imparts 4.8 GHz bandwidth operating between 4 and 8.8 GHz with an average simulated efficiency of 72% and an average gain of 20 dBi throughout the operating band. The specific alignment of the diode polarity enables the model to obtain left-handed circular polarization and/or right-handed circular polarization.
