摘要
A substrate integrated waveguide filter with two reversely arranged square complementary split-ring resonators (CSRRs) etched on the SIW surface is presented in this paper. The proposed filter allow the implementation of a forward-wave passband propagating below the characteristic cutoff frequency of the substrate integrated waveguide. The circuit area of the bandpass filter was only 16 x 16 mm(2). The proposed filter demonstrated a minimum passband insertion loss of 3.5dB and a bandwidth of 5.5% at a center frequency of 5.15 GHz. The filter implementation showed a rejection which was larger than 37 dB at the stopband.
