Abstract: An in-vehicle light apparatus for a vehicle is provided and includes lamp radar units. The lamp unit includes a light source and a reflector arranged around the light source and outputting light from an opening area of the reflector to a predetermined region including in a first direction. The radar unit is provided on a lower or upper side of the lamp unit and includes a circuit board having a board surface arranged in a substantially horizontal state and an antenna unit that transmits an electromagnetic wave and receives a reflected wave in a second direction. The opening area extends in a third direction different from the first direction and the second direction in plan view, and a direction perpendicular to the second direction on the board surface is a direction intersecting the first direction and non-parallel to the third direction.

Abstract: A dielectric substrate for transmitting a signal with a frequency f0 includes a dielectric and a copper film pattern arranged on a first surface of the dielectric. The copper film pattern has a first dimension L in a direction parallel to a propagation direction of an electromagnetic wave that has the frequency f0 and that propagates on the first surface, and the first dimension L is given by: L = 1 ɛ r - 1 k λ 0 where εr represents a relative permittivity of the dielectric, k represents a constant in a range of 0.15 to 0.70, and λ0 represents a free space wavelength of the signal.

Abstract: An array antenna device of this disclosure includes a substrate, a strip conductor with a linear-shape, which is provided on the substrate, and a power feeder that feeds power to the strip conductor, and a plurality of loop elements, a conductor plate, and a plurality of feeding elements. The plurality of loop elements are provided on a first surface of the substrate, and are located along the strip conductor with a specified spacing from each other. Each of the plurality of loop elements has a loop-shape with a notch. The plurality of feeding elements are connected to the strip conductor, and each has a shape extending along a portion of an outer edge of corresponding one of the plurality of loop elements. The conductor plate is provided on a second surface of the substrate.

Abstract: A wireless device that suppresses deterioration of antenna characteristics and can be made thin is provided. The wireless device is provided with a substrate, a wireless module that is mounted on the substrate and has an antenna unit, and a casing that accommodates the substrate and the wireless module. The wireless device has a gap of a length that is an approximate multiple of a half-wavelength of a radio wave corresponding to a communication frequency of the antenna unit, from the antenna unit toward the casing.
