Wideband Bandpass Filters Using Half-Mode Corrugated Substrate Integrated Waveguide

This article presents a novel wideband bandstop filter using a half-mode corrugated substrate integrated waveguide (HM-CSIW) coupled with hexagonal ring resonators (HRRs). The HM-CSIW is designed to operate at the TE10 mode with a cut-off frequency of 22 GHz. The device is fed with integrated digitated capacitor (IDC) in microstrip feed to achieve a full DC-bias. A reconfigurable bandstop behavior has been reported with the introduction of HRR defects within the CSIW. A simulated insertion loss < 1 dB is shown for the passband of the HM-CSIW with a rejection > -30 dB for the stop-band at 26.5 to 33.5 GHz.
