Abstract
A transition for providing connection between a stripline transmission line which is buried in a substrate and the surface of the substrate where components are mounted. A three-wire line disposed orthogonally to the stripline is directly connected to the stripline. The center wire of the three-wire line is connected to the stripline center conductor strip, and the two ground wires are connected to the upper and lower ground planes of the stripline. The center wire of the three-wire line passes through an open area formed in the upper stripline ground plane. To improve the performance of the transition, mode conversion between the electric field configuration of stripline and the electric field configuration of three-wire line is provided, by terminating one ground wire at the upper stripline ground plane. The transition can be used to connect to a conductor-backed coplanar waveguide transmission line circuit formed on the substrate surface.
