Abstract
An antenna element has parallel first conductor and second conductor connected by a short-circuit conductor to form a loaded inductance. A ground conductor is also formed on an outer surface of a device substrate which is formed with a conductive line comprised of the first conductor, second conductor and short-circuit conductor. The ground conductor has a terminate end connected to the conductive line, and is applied with a ground potential at a leading end. Since the ground conductor functions in a manner similar to a conventional short pin, the antenna element can provide a radiation resistance twice as much.
