Consequently, the antenna elements 12a and 12b can be arranged automatically in the planes of the cases 11a and 11b, respectively, by opening the luggage, when required. Therefore, this portable L-shaped antenna can be used readily of place of presentation or show, in which the antenna must be moved, because the antenna can be moved in the same state as a luggage-carry state.
