In this paper, the potential use of split ring resonators (SRRs) to design very compact dual-band bandstop waveguide fllters is proposed. Two square SRRs are placed on the same transverse plane realizing two independent reject bands. By adjusting the SRRs lengths, the stopbands can be targeted at the desired frequencies. In addition, a simple circuit model for this resonator is introduced. Good agreement between the experimental and full-wave simulated results has been achieved.
