PROBLEM TO BE SOLVED: To provide an antenna structure wide in bandwidth and small in volume, and a wireless communication device including the antenna structure.SOLUTION: An antenna structure according to the present invention includes a feed-in terminal, a ground terminal, a first radiator, a second radiator, and a third radiator. The ground terminal and the feed-in terminal are arranged without being brought into contact each other. Both of the first radiator and the second radiator are connected to the feed-in terminal, and the third radiator is connected to the ground terminal. The second radiator includes a first connection section and a second connection section which are connected each other, and the third radiator includes a first extension section and a second extension section which are connected each other. The first extension section is arranged to be separated from the first connection section in parallel each other, and the second extension section is arranged to be separated from the second connection section in parallel each other. Thus, current of the second radiator is coupled to the third radiator. |
