Abstract: Disclosed is a device including a first line, a second line including a first section disposed on a first side of the first line and a second section disposed on a second side of the first line, the second side being opposite to the first side and the second section being separate from the first section by a distance, and at least one bridge electrically connecting an end of the first section with an end of the second section and extending across the first line. The device may be a directional coupler that achieves significantly higher directivity than conventional directional coupler structures, and hence, improves power detection accuracy.

Abstract: A waveguide coupling system may include at least one waveguide member retention structure disposed on an exterior surface of a semiconductor package. The waveguide member retention structure may be disposed a defined distance or at a defined location with respect to an antenna carried by the semiconductor package. The waveguide member retention structure may engage and guide a waveguide member slidably inserted into the respective waveguide member retention structure. The waveguide member retention structure may position the waveguide member at a defined location with respect to the antenna to maximize the power transfer from the antenna to the waveguide member.
