PROBLEM TO BE SOLVED: To down-size an antenna device transmitting electromagnetic waves in an arbitrary direction.SOLUTION: An antenna device includes a plurality of antennas 1, a plurality of magnetic oscillation element parts 2 including a magnetic oscillation element, and modulation means 6 for differentiating the phase of high-frequency power, converted from electric energy by two magnetic oscillation element parts 2-1, 2-2, by outputting the externally inputted electric energy to at least two magnetic oscillation element parts 2 while providing a time difference. When the high-frequency power, converted from electric energy by the magnetic oscillation element part 2, is supplied, the antenna 1 transmits electromagnetic waves to the space on the outside of the magnetic oscillation element part 2.SELECTED DRAWING: Figure 1 |
