Novel 3D multilayer waveguide structures for MMIC filter applications are proposed and examined in this paper. Periodic multilayer‐waveguide resonant structures, which can be used for bandpass filters, are presented. The structure has a high Q and supports a simple fabrication process. An MMIC filter based on this proposed periodic‐resonator configuration is designed at 74 GHz using the commercial software package HFSS. The simulated S ‐parameter responses and a photomicrograph of the fabricated monolithic dielectric filled rectangular waveguide on GaAs substrate are presented. © 2005 Wiley Periodicals, Inc.
