Abstract
A coplanar waveguide coupler comprises traces and waveguides, all formed on one layer of multi-layer printed wiring board with the interconnects between said waveguide coupler traces and waveguides are carried on a second layer of said board. A third layer may have a ground plane.
Claims4
A coplanar waveguide coupler comprising:
- a printed circuit board including at least a first layer of dielectric material having coupled conductive traces formed by selectively etching a first metalization layer on one surface of said first layer of dielectric material;
- input and output coplanar waveguides formed by selectively etching said first metalization layer on said one surface of said first layer of dielectric material;
- interconnect conductors formed by etching a second metalization first layer on the other surface of said layer of dielectric material;
- and,
- through vias connecting the interconnect conductors to the conductive traces and the coplanar waveguides.
