There is provided a wireless apparatus with which a communication range may be prevented from being reduced even in a case where the height of the apparatus is restricted. The wireless apparatus includes an antenna device configured by a substrate including a substrate ground and an antenna element provided on the substrate, and a conductor formed into a sideways U-shape. The conductor includes an upper section and a lower section that are disposed along a ground plane and vertically relative to each other, and a middle section that is disposed substantially perpendicular to the ground plane, between one end of the upper section and one end of the lower section. The conductor is disposed such that the upper section, the lower section, and the middle section thereof are near an upper side section, a lower side section, and a lateral side section of the antenna device, respectively. The upper section of the conductor is disposed near the antenna element, and the conductor functions as an antenna due to current being excited in the conductor when power is supplied to the antenna element.

An antenna structure includes a substrate, a plurality of reflective plates, a grounding plate, a radiating member and a plurality of conductive vias. The substrate contains liquid crystal polymer and has opposite first and second surfaces. The reflective plates are arranged in an array on the first surface of the substrate. The grounding plate is arranged on the second surface of the substrate and overlaps with the reflective plates in a normal direction of the substrate. The radiating member is on the second surface of the substrate and does not overlap with the reflective plates in the normal direction of the substrate. The radiating member has an open slot which is defined by a first radiating branch and a second radiating branch that generate at least two different operating frequency bands. The conductive vias respectively penetrate the substrate and connect with the reflective plates and the grounding plate.
