PROBLEM TO BE SOLVED: To provide a magnetic field antenna capable of reducing a magnetic field leaking to other than a desired direction.SOLUTION: Since both branches 11, 12 are directing a z(z+) direction, magnetic lines of force H exist only in that direction, and the magnetic lines of force in a z(z-) direction are very few (magnetic field is extremely small). Consequently, even if there is a metal in the z(z-) direction, disturbance of magnetic field distribution can be reduced extremely. |
