Figure 2

The rectangular single–split resonator used in the quad–band notch filter. (a) The resonator used in the filter with the largest dimensions. Other resonators will be analyzed in the next section. (b) Electric field confinement of the SRR when tested with waveguide ports in CST/MWS. (c) The resonance of the single–split SRR around 3.85 GHz.
