Bandwidth-Controllable Third-Order Band Pass Filter Using Substrate Integrated Full- and Semi-Circular Cavities

Abstrakt

The article presents a novel circular substrate integrated waveguide (SIW) bandpass filter (BPF) with controllable bandwidth. The proposed BPF is configured using two microstrip feedlines, semi- circular SIW cavities, capacitive slots, and inductive vias. The circular cavity is bisected into two halves, with the two copies thereof being cascaded. Two bisected and cascaded structures obtained this way are subsequently connected back-to-back. Finally, by introducing two inductive vias to the circular center cavity, a transmission zero is generated. In order to examine the design concept, a coupling matrix is generated. To demonstrate the theory a third-order BPF is realized, fabricated, and experimentally validated. The BPF prototype features a wide passband of 8.7 %, a low insertion loss of 1.1 dB, and a stopband of 1.5 f0 with a rejection level better than 20 dB.
