[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1 to Figure 2 As shown, a built-in 4G full-band antenna of the utility model includes a feeder line 1 and a ground feeder line 2. The feeder line 1 and the ground feeder line 2 are both arranged in a housing 3 of an electronic device. The feeder line 1 is arranged in the middle of the ground feeder line 2. The ground feeder line 2 is U-shaped and surrounds the feeder line 1. One end of the feeder line 1 extends outward from the U-shaped opening of the ground feeder line 2. A gap 4 is left between the feeder line 1 and the ground feeder line 2.

[0017] The middle of the shell 3 is a feeder line 1, and a ground feeder line 2 is run around it to form a U-shaped direction surrounding the feeder line 1, which is used to couple the low frequency. The thickness and length of the middle feeder line 1 are adjusted to mainly control the high frequency. The ground feeder 2 surrounds the feeder line 1, and the low frequency is adjusted by adjusting the distance and length. The coupled low frequency bandwidth will be much wider than other methods.

[0018] One end of the feeder line 1 extends to one side of the ground feeder line 2 to form a feeder angle 5, and the feeder angle 5 is coupled with the ground feeder line 2. The feeder angle 5 is coupled with the U-shaped ground feeder line 2 to increase the coupling surface between the feeder line 1 and the ground feeder line 2.

[0019] One side 6 of the U-shaped structure of the feeder line 1 and the ground feeder line 2 is arranged on the bottom panel of the housing 3, and the other side 7 of the U-shaped structure of the ground feeder line 2 is arranged on the side panel of the housing 3. The space is fully utilized in the small-volume housing 3, and part of the ground feeder wiring is arranged on the side panel of the housing 3, and the wiring area of ​​the ground feeder line 2 is jointly formed by the side and bottom surfaces of the housing 3.

[0020] The thickness of the feed line 1 is adjusted to adjust the high frequency bandwidth of the antenna. The thickness of the feed line 1 can affect the high frequency bandwidth.

[0021] The high frequency of the antenna is adjusted by adjusting the length of the feed line 1. The longer the length of the feed line 1 is, the lower the high frequency is.

[0022] Adjust the length of the ground feed line 2 to adjust the low frequency of the antenna. Adjust the length of the U-shaped ground feed line 2 to control the length of the low frequency; the longer the length of the ground feed line 2, the lower the frequency, and the shorter the length of the ground feed line 2, the higher the frequency.

[0023] Adjust the gap 4 between the ground feeder 2 and the feeder 1 to adjust the low frequency of the antenna. Adjusting the gap can adjust the low frequency bandwidth. Adjust the capacitance according to the gap between the ground feeder 2 and the feeder 1 to adjust the frequency and bandwidth of the low frequency.

[0024] The feeder line 1 and the ground feeder line 2 are arranged in the housing 3 by LDS process or FPC process. This product adopts LDS (laser direct structuring) process, and can also use FPC (flexible circuit board) process to produce the feeder line 1 and the ground feeder line 2 structure with specific routing in the housing 3.

[0025] The utility model uses a single-panel FPC and LDS structure to realize the antenna generation inside the housing 3, and uses a specific feeder line 1 and ground feeder 2 to route to meet the needs of a small-area 4G full-band antenna. Under the same conditions, the low-frequency band can be widened a lot. It solves the problem that the existing antenna area is small, the clearance area is small, and the bandwidth requirement is wide.

[0026] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
