Abstract

This paper presents the design and analysis of a high-gain, metamaterial-inspired antenna with frequency reconfigurability, targeting multiband operation across the C and X bands for modern wireless communication applications. The proposed antenna incorporates Complementary Split-Ring Resonators (CSRRs) within a rectangular patch to achieve frequency agility, enhanced impedance matching, and improved radiation performance. Simulated on a FR4epoxy substrate, the antenna is equipped with a PIN diode to enable dynamic switching between operational states. In the ON state, the antenna resonates at 4.84 GHz, 7.97 GHz, and 8.69 GHz, delivering peak gains of up to 6.83 dB with stable, directional radiation patterns in both E-plane and H-plane. In the OFF state, the resonant band shifts to 5.34–5.75 GHz, maintaining a moderate gain of 4.53 dB and consistent radiation behavior. Ansys HFSS simulation software is used to assess the antenna's performance, and important parameters like gain, radiation patterns, and S-parameters are carefully examined. Findings show that the antenna has acceptable gain characteristics, a broad bandwidth, and efficient frequency reconfigurability, making it a viable option for IoT and radar systems and Satellite communications.
