We propose a new type of miniaturized filter to be constructed in multilayer structure. The filter consists of a couple of quarter-wavelength resonators. Each resonator is composed of two segments of coplanar waveguide(CPW) which are fabricated face to face on both surfaces of the substrate. The two resonator segments are connected to each other with a piece of bonding wire at an open end. It possesses sharp band-pass characteristics with an attenuation pole around the passband. We investigate the filtering characteristic through experiments as well as numerical simulations by means of the FD-TD method, and discuss the attenuation pole characteristics in terms of the input susceptance.
