Abstract
This work presents the design of a new wide-band DC-blocking filter in coplanar waveguide (CPW) technology. Compared with the well-known coplanar open-end series stub, the matching of the new filter is theoretically shown to be improved from -10 to -20 dB over the whole W-band. The calculation is made by combining coupled line theory with a simple variational calculation of modal parameters. Measurements carried out in the W-band show very good agreement with the theory
