Abstract:

Novel face to face oriented square complementary split-ring resonators in substrate integrated waveguide (SIW) have been proposed and discussed. In the proposed structures the inner loop of the conventional CSRR is replaced by square and triangular slots . Like the conventional CSRRs the proposed structures allow the implementation of a forward-wave passband propagating below the characteristic cutoff frequency of the waveguide. The proposed designs have the advantages of better pass band and enhanced bandwidth compared to conventional CSRR for applications in miniaturized waveguide bandpass filters.

Keywords: Substrate integrated waveguide (SIW), complementary split-ring resonators (CSRRs), electric dipoles, miniaturised planar waveguide filters.
