Abstract: An antenna module includes a dielectric substrate and a radiating element disposed on the dielectric substrate. The dielectric substrate includes first and second flat portions with different normal directions, and a bending portion that connects the first flat portion and the second flat portion. The bending portion has a bending region having a curvature. The first and second flat portions have a straight region having no curvature. The radiating element is disposed in the first flat portion. In a Raman spectrum obtained by Raman scattering spectroscopic analysis of a cross section of the dielectric substrate, a wave number difference indicating a difference between a wave number which is a mode value in the straight region and a wave number which is a mode value in the bending region is 0.1 cm−1 or more.

Abstract: An antenna module includes a dielectric layer in a form of a flat plate, a ground electrode, a radiating element, and a wiring cable. The ground electrode is arranged on a lower surface of the dielectric layer. The radiating element is arranged on an upper surface of the dielectric layer as being opposed to the ground electrode. The wiring cable faces a side surface of the dielectric layer, and includes a ground electrode and a power feeder line that conveys a radio frequency signal to the radiating element. The wiring cable is smaller in thickness than the dielectric layer. The power feeder line and the ground electrode are electrically connected to the radiating element and the ground electrode, respectively. The ground electrode is arranged at a position different from a position of the ground electrode in a direction of thickness of the dielectric layer.
