Abstract: A first edge of a ground plane extends in a first direction. A radiating element is arranged with a gap from the ground plane in a thickness direction of the ground plane. A feed line supplies a radio frequency signal to the radiating element. A pair of stubs are arranged at positions sandwiching the radiating element in the first direction. The stub is connected to the ground plane. In plan view, a distance from the radiating element to the first edge in a second direction orthogonal to the first direction is ¼ or less of a wavelength corresponding to a resonant frequency of the radiating element. Even when the radiating element is arranged close to an edge of the ground plane, disorder of a beam pattern may be reduced.

Abstract: A radiation conductor is constructed of a metal plate having a pair of main surfaces pointing in opposite directions. Each main surface of the pair of main surfaces includes a first surface region that includes at least part of a peripheral edge portion of the main surface. At least one main surface of the pair of main surfaces includes a second surface region that is a region other than the first surface region. A dielectric member holds the radiation conductor in such a manner that the first surface region of each main surface of the pair of main surfaces is sandwiched between portions of the dielectric member in a thickness direction of the radiation conductor. The second surface region of the at least one main surface is exposed.

Abstract: An antenna module includes a dielectric substrate, a plurality of patch antennas, an integrated circuit, a connector, a heat-radiating member, and connection members. The dielectric substrate includes a first substrate part, a second substrate part, and a third substrate part. The second substrate part is bent toward a rear surface of the first substrate part with respect to the front surface of the first substrate part and the third substrate part is bent toward the rear surface of the first substrate part with respect to the front surface of the first substrate part.

Abstract: Disclosed is a terminal structure of a wiring harness for automobile use that has a profound anticorrosive effect. A terminal member is fixed to an end portion of a coated electric wire such that a crimping portion that the member includes at its one end is crimped around an outer surface of a coating portion of the wire. A resin member is formed to completely cover at least entire outer surfaces of an exposed region at an end portion of the crimping portion (a region including a fracture cross section and a root edge portion) and a region in the vicinity thereof. The resin member is made mainly of an epoxy resin, and a cured material obtained by curing a material having a viscosity from 1000 to 30000 mPa·s at 25 degrees C., which is measured in accordance with the JIS Z8803.

Abstract: An anticorrosive that is capable of delivering high anticorrosive capability. The anticorrosive mainly contains an epoxy resin, and has a viscosity within a range of 1000 to 30000 mPa·s at 25 degrees C., which is measured in accordance with the JIS Z8803. The anticorrosive can be favorably applied to an electrically connected portion between a wire conductor of a coated electric wire with a terminal and a terminal member. The coated electric wire with the terminal has the configuration that the electrically connected portion between the wire conductor and the terminal member is coated with a cured material of the anticorrosive. The epoxy resin is preferably a one-component epoxy resin.
