Abstract :
In this paper, we present the newly developed very compact bandpass filters (BPFs). It is constructed by Capacitive-Gap-Coupled λgo/4 Coplanar Waveguide (CPW) resonators with tapped feed. Furthermore, we present the newly developed compact 4-pole and 6-pole CPW BPFs using this coupled construction. The good agreements are obtained between the simulations and the experimental results.
