Efficient characterization of a CPW series capacitor in Ku Band

The symmetric series gap in the central strip of a Coplanar Waveguide (CPW) is described and characterized for Ku Band applications. The method, based on curve fitting techniques, is proved very efficient for its application domain. The mechanical dimensions of the cell are bounded in order to reduce the cost of production of the line while keeping small transverse dimensions to allow the presence of neighboring lines even in relatively constrained spaces.
