Abstract
An apparatus including a liquid crystal polymer substrate having a top surface and a bottom surface, a coplanar waveguide formed on the top surface of the liquid crystal polymer substrate, the coplanar waveguide having a 90 degree bend with a mitered edge, an inner via positioned adjacent to an inner corner of the 90 degree bend, and an outer via positioned adjacent to the mitered edge of the 90 degree bend, the inner and outer vias positioned along a first plane that is perpendicular to a second plane defined by the mitered edge.
