Patent number: 9705208Abstract: An antenna device includes coil antennas each including a coil conductor wound around a winding axis and a planar conductor that includes at least one edge and that is superposed with at least a portion of each of the coil antennas when viewed in plan. Winding axes of the plurality of coil antennas are parallel or substantially parallel to each other and so as to extend along a surface of the planar conductor, first coil opening ends of coil openings of the coil antennas in a direction in which the winding axes extend are contiguous with the edge and the coil antennas are connected such that magnetic fields generated by the coil antennas are in phase with each other. When W represents a width of the planar conductor, A represents a central spacing of the coil antennas and B represents a distance from a center of a coil antenna to a side of the planar conductor, A?( 3/10)W.Type: GrantFiled: July 20, 2015Date of Patent: July 11, 2017Assignee: Murata Manufacturing Co., Ltd.Inventor: Hiromitsu Ito

Patent number: 9413055Abstract: A base carries a first chip and a second chip oriented differently with respect to the base and packaged in a package. Each chip integrates an antenna and a magnetic via. A magnetic coupling path connects the chips, forming a magnetic circuit that enables transfer of signals and power between the chips even if the magnetic path is interrupted, and is formed by a first stretch coupled between the first magnetic-coupling element of the first chip and the first magnetic-coupling element of the second chip, and a second stretch coupled between the second magnetic-coupling element of the first chip and the second magnetic-coupling element of the second chip. The first stretch has a parallel portion extending parallel to the faces of the base. The first and second stretches have respective transverse portions extending on the main surfaces of the second chip, transverse to the parallel portion.Type: GrantFiled: August 27, 2014Date of Patent: August 9, 2016Assignee: STMICROELECTRONICS S.R.L.Inventor: Alberto Pagani
