Abstract:
1. A directional coupler comprising: first and second transmission line segments positioned on a first plane and spaced apart by a first distance; a first ground plane positioned adjacent to the first transmission line segment and on the first plane; a second ground plane disposed adjacent to the second transmission line segment and on the first plane, wherein the first and second transmission line segments are positioned between the first round plane and the second ground plane; third and fourth transmission line segments positioned on a second plane and spaced apart by a second distance, the second plane spaced apart from the first plane; a first conductive segment connecting the first and third transmission line segments; and a second conductive segment connecting the second and fourth transmission line segments, wherein the first and second transmission line segments are configured to couple energy therebetween, and wherein the third and fourth transmission line segments are configured to couple energy therebetween.
