Abstract
In a directional coupler having flaps on a pair transmission lines to be coupled, structural characteristics such as the distance between adjacent flaps, the length and width of a flap, the direction of projection of the flaps, and whether and to what degree the flaps on the two transmission lines overlap can be selected in order to optimize electrical characteristics of the coupler.
Claims33
A microwave directional coupler comprising:
- a first conductor comprising a first transmission line;
- a second conductor comprising a second transmission line, the second conductor spaced apart from but parallel to the first conductor;
- a plurality of spaced-apart flaps projecting from the first conductor;
- and
- a plurality of spaced-apart flaps projecting from the second conductor, the second-conductor flaps being non-coplanar with the first-conductor flaps,
- wherein at least a portion of the first-conductor flaps overlaps with and is capacitively coupled with at least a portion of the second-conductor flaps without contact therewith.
