Abstract :
A novel substrate integrated waveguide bandpass filter with circular cavity is proposed in this paper. Two circular cavities based on Substrate Integrated Waveguide are connected via connect hole. The width of the hole can control the coupling between resonators. Two different complementary Split Ring Resonators are loaded at input and output feed line to produce transmission zeros and improve the characteristic of the stopband. All the design procedure are given and verified by the experimental results.
