PROBLEM TO BE SOLVED: To provide a small size antenna device capable of operating in a multiple bands as well as wideband.SOLUTION: A radiation element 1 has a first end and a second end connected to a power supply point P1; a radiation element 2 has a first end and a second end connected to a grounding point P2; and the radiation elements 1 and 2 include a portion which extends toward +x direction and gets closer to each other. The radiation element 1 has branching radiation elements 3 and 4 branching at a branching point B1 located at a second end of the radiation element 1; the branching radiation element 3 includes a portion extending toward the +x direction; and the branching radiation element 4 includes a portion extending toward the x direction. The second end of the radiation element 2 is connected to a connection point A1 different from the branching point B1 in the branching radiation element 3. When the antenna device operates at a low band frequency F1, the radiation elements 1 and 2 and the branching radiation element 3 resonate with each other; and when the antenna device operates at a middle band frequency F2, the branching radiation element 4 resonates. |
