Abstract

This manuscript introduces an advanced architecture for a reconfigurable band-pass filter, utilizing substrate-integrated waveguide (SIW) technology. To induce a transmission zero in the passband response of the filter, the design involves coupling two identical open-loop ring resonators in a back-to-back configuration on top of the SIW cavity. The work includes a comprehensive investigation of the variation in notch frequency with respect to the ring diameter. Further incorporating PIN diodes into the structure enabled the realization of a reconfigurable filter that can be switched between a broad passband and two narrow passbands with a notch. Also, a planar DC biasing network has been specifically designed to bias the diodes. Additionally, a prototype has been developed to validate the concept and the performance in terms of reflection and transmission coefficients. The miniaturized reconfigurable filter design presented is well suited for the use in both Ku- and K-band applications due to its specific performance characteristics.
