PROBLEM TO BE SOLVED: To provide an antenna device capable of downsizing and changing over directivity.SOLUTION: An antenna device (100) includes a radiation element (1) and a reflective element (2) separated into a plurality of conductors (3, 4). A first state in which the plurality of conductors (3, 4) are brought into contact with each other and a second state in which the conductor (4) is moved from the first state and brought into non-contact with the conductor (3) can be changed over.SELECTED DRAWING: Figure 1 |
