Directional couplers are provided. In one embodiment, the directional coupler includes first and second transmission line segments positioned on a first plane and spaced apart by a first distance, 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, where the first and second transmission line segments are configured to couple energy therebetween, and where the third and fourth transmission line segments are configured to couple energy therebetween. |
