Abstract: A wireless communication apparatus includes a first wireless communication unit performing a first type wireless communication and a second wireless communication unit performing a second type wireless communication, an interference determination portion, and an interference suppression portion. The interference determination portion determines whether the first wireless communication unit is in an interference state based on a radio wave reception state of the first wireless communication unit acquired when the second wireless communication unit is in a transmitting state. In the interference state, radio waves received by the first wireless communication unit are interfered by the radio waves transmitted from the second wireless communication unit. The interference suppression portion executes an interference suppression process in response to the interference state by suppressing the radio waves transmitted from the second wireless communication from interfering with the radio waves received by the first wireless communication unit.

The board has an antenna element section and is stood on a surface of the base. The circuit section serves as at least part of a wireless communication circuit electrically connected to the antenna element section. The housing is made of a resin material and forms a projection of a vehicle outer shape. The board and the circuit section are located in space formed by the base and the housing. The board is stood on the surface of the base so that a first direction perpendicular to the surface of the base differs from a second direction equal to a thickness direction of the board. The circuit section implemented on the board at a position away from the base in the first direction.

Abstract: An antenna device includes a ground plate, a patch portion disposed parallel to the ground plate with a particular spacing, a plurality of short circuit portions that electrically connect the patch portion to the ground plate, and a loop portion which is a loop shaped conductor member at a particular spacing from an outer edge portion of the patch portion. The patch portion has an area which forms an electrostatic capacitance that causes parallel resonance with an inductance provided by the short circuit portions at a particular target frequency. The loop portion is formed with a perimeter length which is an integral multiple of the wavelength of radio waves at the target frequency. A feed point is disposed on the loop portion, and current is supplied to the patch portion through the loop portion.
