Abstract (en)
A coplanar waveguide filter is disclosed including a pair of grounded conductors (36) disposed on a surface (34) of a dielectric substrate equidistant from a transmission center line (42), and first (30) and second (32) conductors on said substrate surface (34) between said grounded conductors (36) and symmetrically disposed with respect to the transmission center line (42) by virtue of one conductor (32) being bifurcated, and the other not. The structure produces coupled sections of coplanar waveguide transmission lines which are both physically and electrically symmetrical. Solutions for the even and odd-mode impedance are given, allowing synthesis of a wide range of filter functions.
