Abstract: There is provided a simple configuration capable of feeding power to a conductor present between a pair of dielectric plates.
A feeding structure including a first dielectric plate; a second dielectric plate that faces the first dielectric plate; an interlayer that is disposed between the first dielectric plate and the second dielectric plate; a conductor that is disposed between the first dielectric plate and the second dielectric plate; a feeding portion that is disposed on a side opposite of the interlayer from the first dielectric plate and that sandwiches at least one of a portion of the interlayer and a portion of the second dielectric plate between the conductor and the feeding portion; and a first transmission line that is connected to the feeding portion, wherein the feeding portion electromagnetically couples to the conductor with a gap smaller than a thickness of the first dielectric plate.

Abstract: A vehicle antenna includes: a vehicle window glass an electronic device provided in a vicinity of a vehicle width direction central portion at or near upper portion of the vehicle window glass; and an antenna attached to the upper portion of the vehicle window glass such that a normal to a radiation surface passes through a principal surface. A vehicle width direction central position of the antenna is separated from a reference position that is a vehicle width direction center of the electronic device.

Abstract: A window glass with a seal member mounted to an opening of a vehicle includes a laminated glass including a vehicle outside glass plate, a vehicle inside glass plate, and an intermediate film; and a seal member arranged in a peripheral portion of the laminated glass. A plate thickness of the vehicle inside glass plate is less than that of the vehicle outside glass plate, and 1.0 mm or less. The vehicle outside glass plate has a shielding layer in a peripheral portion of a vehicle inside surface. In a cross section of the laminated glass perpendicular to an outer peripheral edge, an end of the vehicle inside glass plate is located inward in an in-plane direction with respect to an end of the vehicle outside glass plate. The seal member has a first fixing part that is bonded to the vehicle outside glass plate via the shielding layer.

Abstract: An antenna system for vehicle includes a vehicle and a MIMO antenna that is mounted on the vehicle and that transmits and receives radio waves of a predetermined frequency. The MIMO antenna includes antennas including a first antenna that mainly transmits and receives a first polarized wave and a second antenna that mainly transmits and receives a second polarized wave orthogonal to the first polarized wave, and the antennas are dispersedly arranged on the vehicle. One of the first antenna and the second antenna are arranged based on at least one of (1) a configuration in which one is arranged in a central region and another one is arranged in a first peripheral region or a second peripheral region and (2) a configuration in which one is arranged in a first region and another one is arranged in a second region.
