A multiresonant split ring resonator (SRR) composed of two circular-shaped meandered strips is presented. Resonances are first analyzed by means of eigenmodes computation and field mapping. It is shown that a resonance can emerge from a standing wave taking place in each slot produced by a meandered strip. A slot operates as a two-wire transmission line section short-circuited at one termination and loaded by an open-circuit at the other end. Consecutively, a resonance occurs approximately when a quarter-wavelength matches the length of the slot. A resonance frequency shift is observed, and it is related to a transverse magnetic coupling between a first antisymmetric mode and a second symmetric mode. Finally, multiple resonances in an SRR are experimentally evidenced by spectroscopy of the input impedance of an SRR resonator antenna. Experimental results are favorably compared with simulation.
