Abstract: An electronic device includes a transmission line and a circuit board. The transmission line includes a signal conductor, a base material, a first external connection conductor, a second external connection conductor, and a ground conductor, and defines a stripline. The circuit board includes a first mounting land conductor, a second mounting land conductor, and a radiation reduction conductor. The first mounting land conductor and the second mounting land conductor are provided in a concave portion on the surface of the circuit board, and are respectively connected to the first external connection conductor and the second external connection conductor. The radiation reduction conductor is provided on the lateral surface of the concave portion in which the transmission line is disposed, and is in contact with or adjacent to the first lateral surface and the second lateral surface of the base material.

Abstract: An antenna module includes a resin multilayer substrate including a plurality of base materials that are flexible. The resin multilayer substrate includes a rigid portion at which a first number of stacked layers of the base materials is relatively large and a flexible portion at which a second number of stacked layers of the base materials is relatively small. A radiating element including a conductor pattern is provided at the rigid portion. A transmission line including a conductor pattern and electrically connected to the radiating element is provided at the flexible portion. A frame-shaped conductor that surrounds the radiating element when viewed in a direction in which the base materials are stacked is provided at either the rigid portion or the flexible portion, or both the rigid portion and the flexible portion.

Abstract: A multilayer board includes a flexible base material including laminated insulator layers and curved along an X-axis direction on a plane orthogonal or substantially orthogonal to a lamination direction, an interlayer connection conductor on the flexible base material, and a notch pair on the flexible base material at positions symmetrical or substantially symmetrical in the X-axis direction with respect to a position of the interlayer connection conductor, the notch pair extending in a Y-axis direction orthogonal or substantially orthogonal to the X-axis direction on the plane. The interlayer connection conductor is within a region defined by the notch pair and lines respectively joining ends of the notch pair in the Y-axis direction. A radius of curvature of a region of the flexible base material between the notch pair in the X-axis direction being greater than curvature radii of regions outside of the notch pair.
