In the embodiment, the first radiator 110 is disposed between the second radiator 120 and the ground portion 140, but the embodiment of the invention is not limited thereto. The capacitor structure 160 is electrically connected between the second radiator 120 and the ground 140 to provide an equivalent capacitor between the second radiator 120 and the ground 140. In the present embodiment, the capacitor structure 160 includes a first conductor portion 162 and a second conductor portion 164. The first conductor portion 162 is electrically connected to the second radiator 120, and the second conductor portion 164 is electrically connected to the ground portion 140, wherein a gap 166 is formed between the first conductor portion 162 and the second conductor portion 164 to form the capacitor structure 160.

In the present embodiment, the third radiator 130 is electrically connected to the ground portion 140 through the connecting body 150, so that the third radiator 130 is electrically connected to the ground portion 140. In addition, the first radiator 110, the second radiator 120, the third radiator 130, the ground portion 140 and the connector 150 of the present embodiment are all made of metal. For example, the first radiator 110, the second radiator 120, the third radiator 130, the ground part 140, and the connector 150 may be made of a copper sheet, but the embodiment of the invention is not limited thereto.

When the bias level of the antenna signal AS is higher than the turn-on voltage of the first switch element D1, the first switch element D1 is turned on and electrically connects the first radiator 110 and the second radiator 120. On the contrary, when the bias level of the antenna signal AS is lower than or equal to the turn-on voltage of the first switch element D1, the first switch element D1 is turned off, and the first radiator 110 is electrically disconnected from the second radiator 120.
