This article relates generally to delay lines for electrical signals and more particularly to mechanically variable delay lines wherein the delay line itself is a coplanar waveguide. Referring to the drawing, the system consists of coplanar stripline 10 made of copper, nickel, or other suitable conducting metal laminated onto or otherwise manufactured on a suitable substrate (not shown). The substrate may be in the shape of a disk to allow rotation, or rectangular to allow translation of the substrate. Wideband connection is made to the coplanar stripline 10 by small spring-loaded sliding contacts 12, allowing relative motion of the coplanar stripline 10 and the contacts 12.
