1. A wireless apparatus comprising:
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, wherein
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, when the wireless apparatus is disposed above the ground plane which is a surface of earth,
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, and
the upper section of the conductor is disposed near the antenna element and a long direction of the upper section of the conductor is disposed along a long direction of 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,
wherein the conductor is disposed in such a way that a gap between the middle section of the conductor and the lateral side section of the antenna device is greater than the shortest interval between the upper section of the conductor and the antenna element.
