Abstract
There is adopted an enclosure dipole antenna structure including antenna elements respectively provided in a lower enclosure and an upper enclosure. There is also adopted a structure in which the lower structure and the upper structure are rotatably joined together along two axes of hinges. The enclosures thereby become openable and closable in two directions including a vertical direction and a horizontal direction. There can be implemented high antenna performance without use of an external antenna even regardless of whether the enclosures are opened in the vertical direction or the horizontal direction. A feeding section and a connection section are separated from each other by a distance of 1/20 or more of a wavelength corresponding to an operating frequency. Power can well be fed to the antenna elements.
