A coplanar waveguide broadside end-coupled band-pass filter

Abstract

A new broadside end-coupled bandpass filter using a coplanar waveguide (CPW), suitable for wideband microwave and millimeter-wave integrated circuits, has been developed. The shielded CPW and broadside CPW, employed in the filter, were analyzed using the quasi-static spectral-domain method. An X-band (8-12-GHz) three-resonator bandpass filter has been built and tested with a good agreement between the measured and calculated results.<>
