Abstract: An antenna apparatus includes a dielectric substrate, a feed element, a front array, and side arrays. The feed element, front array, and side arrays are formed on the dielectric substrate. The antenna apparatus includes mounting pads on the dielectric substrate, for coupling the antenna apparatus to another substrate by means of soldering. A part of the mounting pads are formed in a region located in a first direction when viewed from the feed element and front array, with a part of parasitic elements of the side arrays being interposed between these mounting pads and the feed element and front array. The other part of the mounting pads are formed in a region in a second direction when viewed from the feed element and front array, with another part of the parasitic elements of the side arrays being interposed between these mounting pads and the feed element and front array.

Abstract: A communication device includes: a distance information acquisition unit configured to acquire distance information indicating a distance to a communication target; a setting information acquisition unit configured to acquire setting information including a communication distance; and a communication unit configured to communicate with the communication target. The distance information acquisition unit acquires the distance information after the communication unit establishes connection with the communication target. The communication unit cuts the connection with the communication target when the distance information does not satisfy the communication distance included in the setting information.

Abstract: An inter-vehicle communication system is a system that provides communication between vehicles with use of a beam having a directivity and includes a first antenna and a second antenna. The first antenna is provided to a first vehicle, and performs wireless communication. The second antenna is provided to a second vehicle coupled to the first vehicle, and performs wireless communication. The second antenna emits a beam toward the first antenna. In a state where the first vehicle and the second vehicle are aligned to each other, a position in a horizontal direction of the first antenna is different from a position in the horizontal direction of the second antenna.
