PROBLEM TO BE SOLVED: To provide an antenna module capable of being easily manufactured and small in cubic volume.SOLUTION: An antenna module according to the present invention comprises: a circuit board; and an antenna including a ground portion and a feed-in portion for ground and signal feed-in. The antenna module also includes a connection portion, a first resonance portion, and a second resonance portion. The feed-in portion extends from one side of the ground portion and forms one cutout together with the ground portion. The first resonance portion and the second resonance portion are located on the same straight line, and joined to the ground portion and the feed-in portion via the connection portion, respectively. The first resonance portion, the connection portion and the ground portion together form a first gap, and the second resonance portion, the connection portion and the feed-in portion together form a second gap. The first resonance portion sends and receives a signal with a first working frequency by adjusting dimensions of the cutout and the first gap, and the second resonance portion sends and receives a signal with a second working frequency by adjusting dimensions of the second gap. |
