The Complimentary Split Ring Resonator (CSRR) is now popular in microwave devices. However, the analytical interpretations of its resonance frequencies, especially that with finite grounds, remains elusive. We demonstrate in this letter a novel method of unveiling the resonance mechanisms of antennas loaded with a finite-grounded CSRR (FG-CSRR) based on the equivalent circuit models. As a proof-of-concept, a triple-band antenna with FG-CSRR structure is explored, whose inner patch is loaded with additional elements with negligible impact on the inherent resonances of FG-CSRR. Various FG-CSRR-loaded antennas with different parameters are furthermore applied to validate our method. The proposed analytical model would facilitate the design of the operating mechanism of these antennas. Moreover, less metallic coating and the independent resonances of FG-CSRR promise its suitability for miniaturized microwave systems.
