Abstract
The antenna device includes: an element parthaving an excitation element, a first passive elementhaving first and second conductive partsand, a second passive elementhaving third and fourth conductive partsand, a first switchcontrolling conduction between the first and second conductive parts, and a second switchcontrolling conduction between the third and fourth conductive parts; and a controlleroutputting an electric signal for controlling conduction of the first and second switches. The controller outputs identical DC signal to the first and second switches, and one of the first and second switches is brought into conduction while the other one is brought out of conduction.
