摘要： 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.

摘要： An antenna device includes a printed circuit board including a circuit configured to determine a position based on a navigation signal, and a dipole antenna element mounted on the printed circuit board and configured to receive the navigation signal. Further, the antenna device includes an L-shaped parasitic antenna element, wherein the dipole antenna element and a long-side element of the L-shaped parasitic antenna element are placed parallel to each other but at a position not in line with each other, and an end of a short-side element of the L-shaped antenna element is placed in close proximity to an end of the dipole antenna element.
