ABSTRACT:
A stripline coupler exhibiting higher coupling coefficients and improved ttering properties in the plus 10 Ghz range, utilizes a section of discrete areal dimension in each of two tapered striplines, such that said sections form a discontinuity in the taper, in conjunction with perforations of the bilateral ground planes coincident with each section. The dielectric separating each stripline from the ground plane is modified in the region of the perforations to reduce the dielectric constant in the region.
