More specifically, the main radiation portion 120 and the grounding portion 130 both extend toward the first direction D1 and have a first gap G1 therebetween along the second direction D2, and the main radiation portion 120 and the grounding portion 130 can be in resonance by coupling through the first gap G1. The floating portion 140 also extends toward the first direction D1, and is the second gap G2 apart from the grounding portion 130 along the second direction D2, and the grounding portion 130 and the floating portion 140 generate resonance through coupling via the second gap G2. The floating portion 140 may further include an extension segment 141. The antenna structure 100 may add the extension segment 141 to the floating portion 140 according to the environmental space, and the length and shape of the extension segment 141 can be adjusted according to the required bandwidth, so as to extend the low-frequency bandwidth of the antenna structure 100, but the present disclosure is not limited thereto.
In addition, the antenna structure 100 may further include a branch radiation portion 160. The branch radiation portion 160 is connected to the main radiation portion 120 and extends toward the first direction D1. The branch radiation portion 160, the main radiation portion 120, the grounding portion 130 and the floating portion 140 are arranged in order along the second direction D2.
The main radiation portion 120 has a first resonance frequency, the grounding portion 130 has a second resonance frequency, the floating portion 140 has a third resonance frequency, and the branch radiation portion 160 has a fourth resonance frequency. The first, second, third, and fourth resonance frequencies do not overlap. Further, the first resonance frequency is generated by the main radiation portion 120, which is between 2.3 GHz and 2.69 GHz, and the second resonance frequency is generated by the resonance of the main radiation portion 120 and the grounding portion 130, which is between 1.7 GHz and 2.3 GHz. The third resonance frequency is generated by the resonance of the main radiation portion 120, the grounding portion 130 and the floating portion 140, which is between 1.4 GHz and 1.7 GHz, and the fourth resonance frequency is 3 GHz. Hence, the antenna structure 100 of the present disclosure can broaden the low-frequency band of the antenna structure 100 in a limited space. The structure of the antenna structure 100 will be illustrated below by a more detailed embodiment.
Specifically, the main radiation portion 120 and the grounding portion 130 can be T-shaped or L-shaped, but the present disclosure is not limited thereto. The main radiation portion 120, the grounding portion 130 and the floating portion 140 are partially overlapped in a vertical projection direction DP. In other words, the second segment 122 of the main radiation portion 120, the fourth segment 132 of the grounding portion 130 and the floating portion 140 partially overlap along the vertical projection direction DP. In addition, the grounding portion 130 and the floating portion 140 partially overlap by a section in the vertical projection direction DP, and the section has an overlap length greater than or equal to one-fifth of a length of the floating portion 140. Specifically, a section of the fourth segment 132 and a section of the floating portion 140 that overlap in the vertical projection direction DP has an overlap length L1, and the overlap length L1 is greater than or equal to one-fifth of the length L2 of the floating portion 140, but the present disclosure is not limited thereto, the overlap length L1 can be adjusted according to the required frequency and space limitation. The second segment 122 of the main radiation portion 120 couples with the branch radiation portion 160.
