Abstract :
In this paper, a k-band oversized folded half mode substrate integrated waveguide filter is proposed. The cross coupling between the TE10 and TE20 in one resonator without additional structure is used to generate transmission zeros in stopband to improve filter performance, and the folded half mode SIW is used for cutting down the filter size. The results show this method is very helpful in reducing the filter size and enhancing filter selectivity.
