A new compact IgO/4 coplanar waveguide resonator bandpass filter

This paper presents newly developed compact ?g0/4 coplanar waveguide resonator bandpass filters (CPW-BPF). Furthermore, a method for suppressing spurious resonance responses of the filters is discussed The experimental results are given of the new CPW-BPFs and compared with the simulations to check the pass band response and the spurious resonance responses The good agreements are obtained between them.
