Abstract
The resonant frequency determined by octagonal split resonant rings (SRRs) is presented and analyzed. The simulated results show that the resonant frequency improves when the opening size of the SRRs becomes larger, and that enhancement of the coupling degree can improve the resonant frequency and widen the band. Four samples are designed to implement the experimental measurement. The results show that the bandwidth of the resonant frequency becomes wider when the thickness of the substrate becomes thinner, and the resonant frequency is shifted by changing the cell size. It is demonstrated that the experimental results show good agreement with the theoretical analysis.
