Design of a SIW Bandpass Filter Using Defected Ground Structure with CSRRs

Design of a SIW Bandpass Filter Using Defected Ground Structure with CSRRs

In this paper, a substrate integrated waveguide (SIW) bandpass filter using defected ground structure (DGS) with complementary split ring resonators (CSRRs) is proposed. By using the unique resonant properties of CSRRs and DGSs, two passbands with a transmission zero in the middle have been achieved...
