Multi-band Antenna

Abstract

To provide a multiband antenna which allows size reduction.SOLUTION: A first slot edge part 201 and a second slot edge part 203 of a conductor main part 20 have their longitudinal sides in a first direction, and they are located with a slot 22 sandwiched therebetween in a second direction. An open part 24 is formed at a portion different from the first slot edge part 201, and it opens the slot 22 to the outside of the conductor main part 20. A first portion 301 of a radiation element 30 extends from an end 2011 of the first slot edge part 201 in the second direction. A second portion 303 of the radiation element 30 extends from an end of the first portion 301 in the first direction. An additional element 40 passes from the second portion 303 through a first specific region 70 without making contact with the conductor main part 20 and extends toward a second specific region 75. The first specific region 70 is a region which overlaps a portion of the first slot edge part 201 in a third direction, and the second specific region 75 is a region which overlaps a portion of the second slot edge part 203 in the third direction.SELECTED DRAWING: Figure 2
