Abstract

A new compact integrated tapped‐line combline filter, with metal‐insulator‐metal (MIM)‐type capacitive loads, is designed and fabricated using newly proposed micromachining techniques that employ a polyimide dry film as a dielectric layer. For increased uniformity of thickness, a dry‐film fabrication process is developed. The presented filter is realized with a relatively small size, 3.68 by 4.53 mm, on a polyimide dry film and shows up to 50% size reduction as compared with a general quarter‐wavelength filter. © 2004 Wiley Periodicals, Inc.
