Abstract

This paper presents a novel coplanar waveguide (CPW) dual pass band and triple pass band filter using the split-modes of the loaded stub square loop resonators. With the CPW feeding line, two micro strip stub resonators built on the rear sides are used to suppress resonance. We have designed our filter on the FR4 substrate (permittivity = 4. 4 and loss tangent=0. 02) with 20x50mm square and thickness 0f 1mm only. The modes splitting characteristics of the proposed structure are analyzed. A triple pass band filter covering center frequencies of 21. 5 GHz, 26. 7 GHz and 33. 1 GHz or (K band range) is designed to verify the validity of the methodology. Good agreement for simulated results.
