A novel bandstop waveguide filter, using split ring resonators, is proposed. Split ring resonators are implemented as printed-circuit inserts in a form of reduced dielectric plates, providing better performance in terms of return loss beyond the stop band, compared with the structure where dielectric plates across the entire transverse cross-section are applied. The filter response is analyzed depending on the various parameters of the resonators. These resonators are used for the design of third-order bandstop waveguide filter for single resonant frequency. Also, a novel design of multi-band bandstop waveguide filter is developed and dual-band bandstop waveguide filter of the third order, using split ring resonators, is presented as an example.
