A novel narrowband filter with cross-coupling is presented. By taking advantage of the structure of multilayered substrates, two substrate integrated circular cavities (SICCs) are stacked, and cross-coupling is realized between the two resonators by different slots in the middle layer. Because of the cross-coupling structure, two transmission zeros (TZs) are introduced in the out-of-band region, allowing the frequency selectivity to be improved. The simulated insertion loss at the central frequency of 33 GHz is approximately 3 dB and the 3- dB bandwidth is 0.4 GHz. The structure is simple to fabricate and practical for use in system-in-packaging applications.
