A Complementary Split Ring Resonator (CSRR) Based Metamaterial Structure for Antenna and Size Reduction Applications

This paper presents the design and simulation of a Complementary Split Ring Resonator (CSRR)-based metamaterial structure aimed at enhancing antenna performance for wireless communication applications. The CSRR is integrated into a microstrip patch antenna to optimize impedance matching, bandwidth, size and efficiency. Utilizing Rogers RT/duroid 5870 as the substrate, the proposed design ensures low dielectric loss and improved radiation characteristics. The extracted material parameters confirm negative permittivity at resonance, validating the metamaterial behavior. The results indicate that CSRR structures can effectively contribute to antenna miniaturization while maintaining high radiation efficiency, reduce size, making them suitable for modern wireless communication and RF applications.
