Abstract

A novel dual‐mode filter using circular high‐order mode cavities based on substrate integrated waveguide technology is presented. Its dual‐mode character and transmission responses are carefully investigated. Filters in both Ka‐ and Q‐band using two congruent cavities in folded configuration are designed, fabricated with standard PCB process, and measured. Small insertion loss, flat group delay, and good tolerance are observed, which is consistent with the simulation. © 2009 Wiley Periodicals, Inc.
