Abstract: In an antenna element, a planar ground conductor layer on an insulation substrate is connected to ground. A radiation conductor layer radiates and/or receives high-frequency signals. The radiation conductor layer is in or on the insulation substrate and above the planar ground conductor layer. A lower principal surface of the radiation conductor layer overlaps an upper principal surface of the planar ground conductor layer as viewed in an up-down direction. The ground conductor is in the insulation substrate and connected to the ground potential. An upper end of the ground conductor is above the radiation conductor layer. The ground conductor layer is spaced away from the radiation conductor layer as viewed in the up-down direction. Only a conductor through which the high-frequency signals are transmitted and a conductor connected to the ground potential are between the ground conductor and the radiation conductor layer.

Abstract: An inductor bridge includes a flexible substrate and a coil defined by a conductor pattern provided on or in the flexible substrate, and connects a plurality of circuit portions. The flexible substrate includes a rigid portion and a flexible portion, the rigid portion being wider than the flexible portion. The rigid portion includes the coil and a joining portion connected to another circuit. The coil includes two coil portions located at different positions in plan view, a flexible portion is located adjacent to one side of the rigid portion, and at least two coil portions of the plurality of coil portions are located on the one side when viewed from the joining portion.

Abstract: A transmission line includes a substrate including insulator layers, a mounting electrode on a front layer of the substrate, a signal conductor, a first ground conductor, a first connecting electrode that electrically connects the mounting electrode and the signal conductor and is between the signal conductor and the first ground conductor in a laminating direction, a first inter-layer connecting conductor that is electrically connected between the mounting electrode and the first connecting electrode and is bonded to the first connecting electrode, and a second inter-layer connecting conductor that is electrically connected between the signal conductor and the first connecting electrode, is bonded to the first connecting electrode, and does not overlap with the first inter-layer connecting conductor when viewed in the laminating direction. The first ground conductor does not overlap with at least a portion of the first connecting electrode when viewed in the laminating direction.
