Apparatus for wideband transmission conversion from coplanar waveguide to parallel transmission line
First Claim
1. A transmission line conversion apparatus, comprising:
- a coplanar waveguide (CPW) comprising a transmission line, wherein the transmission line comprises a signal line and a ground line; and
a parallel transmission line connected to the CPW at a predetermined angle with respect to a substrate constituting the CPW, wherein the parallel transmission line comprises a signal line and a ground line.

Abstract
A transmission line conversion apparatus connecting a parallel transmission line to a coplanar waveguide (CPW) is provided. To this end, the CPW including a transmission line composed of a signal line and a ground line which is formed on one surface of a dielectric substrate, and a parallel transmission line connected to the CPW, at a predetermined angle with respect to a substrate constituting the CPW, and composed of a signal line and a ground line, are proposed. In addition, the signal line of the CPW and the signal line of the parallel transmission line are connected to each other, and the ground line of the CPW and the ground line of the parallel transmission line are connected to each other. As such, by connecting the CPW to the parallel transmission line, a return loss can be minimized.
