Abstract: An antenna device includes a power feeding portion; and an antenna including first and second antenna parts, and an amplifier each electrically connected to the power feeding portion. The first antenna part includes a first element including a part extending in a first direction, and a first loop element connected to an end of the first element. The second antenna part includes a second element including a part extending in the first direction, and a second loop element connected to an end of the second element. The first loop element includes a part extending in the first direction, and a part extending in the second direction different from the first direction. The second loop element includes a part extending in the first direction, and a part extending in a third direction opposite to the second direction. The first and second loop elements are positioned apart from each other.
