A mobile device includes a dielectric substrate, a ground plane, an RF (Radio Frequency) module, an antenna structure, a bypass inductor, matching circuits, and a switch circuit. The antenna structure includes a first radiation element and a second radiation element. The first end of the first radiation element is connected to the RF module, and the second end of the first radiation element is open. The second radiation element is separate from the first radiation element. The first end of the second radiation element is open and adjacent to the first radiation element, and the second end of the second radiation element is connected through the bypass inductor to the ground plane. The switch circuit selects one of the matching circuits according to a control signal. The second end of the second radiation element is further connected through the selected matching circuit to the ground plane. |
