In this letter, a vertical split-ring resonator (VSRR) based on a coupled coplanar waveguide (CCPW) is proposed to reduce the longitudinal length of a VSRR. The resonant condition of the proposed resonator is obtained using the transmission line theory and the odd-mode analysis. The longitudinal length of the resonator is reduced using the CCPW. From full-wave simulations, the relationship between the loaded bandwidth and design parameters is investigated. The proposed design to miniaturize the resonator was fabricated and measured, and it is verified that the effective longitudinal length of the proposed VSRR based on CCPW is reduced by 50% compared with the previous VSRR.
