Abstract

A novel multilayered cross‐coupled substrate‐integrated waveguide (SIW) circular cavity filter is proposed in this letter. The filter is designed using standard low‐temperature co‐fired ceramic (LTCC) technology, with the fractional bandwidth of 0.25% obtained, can operate at 20 GHz and have two finite frequency transmission zeros at 19.51 and 20.51 GHz, respectively. Measured results show good agreement with simulated results and validate the structure of the proposed filter. © 2009 Wiley Periodicals, Inc.

## Abstract This letter presents the design, implementation and experiment of planar and multilayer three‐pole cross‐coupled bandpass filters realized by substrate‐integrated waveguide (SIW). The two three‐pole filters centered at 10 GHz with one transmission zero are simulated by using full‐wave e
