Patent abstract
An antenna includes a first radiating element (2a), a second radiating element (2b), a third radiating element (2c), a first switch element (7-1) for switching an electrical connection between the first radiating element (2a) and the second radiating element (2b), a second switch element (7-2) for switching an electrical connection between the second radiating element (2b) and the third radiating element (2c). The first radiating element (2a), the second radiating element (2b) and the third radiating element (2c) are conductor patterns formed on a dielectric member (1) that is separate from a printed circuit board (4) and has a dielectric constant larger than that of the printed circuit board (4).
