The first main radiation part 111 connects the first main feeding part F1, the first coupling part 112 and the first regulated part 113.

The control mode of the plurality of electrode states is, for example, that the first regulating part 13 has a plurality of first switches (not shown in the figure) for controlling the plurality of first electrode states, but is not limited to this.

Please refer to Figure 13 , the states one, two, three and four of the main antenna 11 basically do not affect the operating state near 1.5GHz and above 1710MHz, and can all meet the specification requirements of the corresponding frequency band.
[0037] In addition, the first coupling part 112 and the ground G are not connected to each other, the first coupling part 112 is coupled to the ground G in a capacitive coupling manner, in other words, the first coupling part 112 and the ground G form a coupling capacitor. Furthermore, the first conductor 131 and the first regulated part 113 of the main antenna 11 are not connected to each other, and the first conductor 131 is coupled to the first regulated part 113 in a capacitive coupling manner. Furthermore, preferably, the main antenna 11 and the sub-antenna 12 are both fed by the coaxial cable, as shown in Figure 3 .
[0038] Please refer to Figures 7 to 11 ,Figures 7 to 10 is a schematic view of the front, back, top and bottom view of the second antenna group 2, Figure 11 is a perspective view of the second antenna group 2, Figure 11 is mainly to show the structure of the back (rear surface) and the top (upper surface). The main complementary antenna 21 has a second main radiating portion 211, a second coupling portion 212 and a second tuning portion 213. The second main radiating portion 211 connects the second main feed-in portion F3, the second coupling portion 212 and the second tuning portion 213. The auxiliary complementary antenna 22 has a second auxiliary feed-in portion F4, which, after being fed by a coaxial cable, is coupled to the main radiating portion of the auxiliary complementary antenna 22 in a coupling manner, but is not limited thereto. The second auxiliary feed-in portion F4 can also be directly connected to the main radiating portion of the auxiliary complementary antenna 22. In an embodiment, the main complementary antenna 21 and the auxiliary complementary antenna 22 jointly comply with the operating frequency bands of frequency band numbers B3, B4, B66, B9, B39, B2, B25, B1, B34, B40, B30, B41, B7, B38, n78, n77, B42, B48, B43, n79, B46. Furthermore, the second coupling portion 212 is coupled to the ground G, and the second tuning portion 23 has a second conductor 231 coupled to the second tuning portion 213, and the second tuning portion 23 has a plurality of second electrode states. The second tuning portion 23 is an active tuning circuit that actively adjusts the operating mode of the main complementary antenna 21, especially the operating mode in the low frequency range of 698MHz-960MHz. Similar to the main antenna 11, please refer to Figure 12 for details. The states one, two, three and four generated by the change of the operating mode can jointly meet the specification requirements (efficiency) in Figure 12 . The control mode of the plurality of electrode states is, for example, that the second tuning portion 23 has a plurality of second switches (not shown in the figure) for controlling the plurality of second electrode states, but is not limited thereto. The second electrode states make the main complementary antenna 21 operate in a plurality of second modes, and the operating frequency bands of the plurality of second modes jointly comply with the operating frequency bands of frequency band numbers B12, B29, B28, B13, B14, B26, B19, B18, B5, B6, B20, B8. Please refer to Figure 13 for details. The states one, two, three and four of the main complementary antenna 21 basically do not affect the operating state near 1.5GHz and above 1710MHz, and can all meet the specification requirements of the corresponding frequency bands.
[0039] Furthermore, the second coupling section 212 is not connected to the ground G; the second coupling section 212 is capacitively coupled to the ground G. In other words, the second coupling section 212 and the ground G form a coupling capacitor. Moreover, the second conductor 231 is not connected to the second modulated section 213 of the main complementary antenna 21; the second conductor 231 is capacitively coupled to the second modulated section 213. Furthermore, preferably, both the main complementary antenna 21 and the sub-complementary antenna 22 are fed using coaxial cables, such as... Figure 8 As shown.
[0040] Based on the above, the first thing to note is that... Figure 1 The embodiment shows that the structure of the first antenna group 1 and the structure of the second antenna group 2 are not completely symmetrical. After subtracting the slight differences in the wiring of the antenna patterns (these differences are due to minor modifications and adjustments made for product requirements), in... Figure 6 The first antenna group 1 and in Figure 11 The first major difference in the second antenna group 2 is that the first circuit board 130 of the first control unit 13 is on the front of the first antenna group 1, while the second circuit board 230 of the second control unit 23 is on the back of the second antenna group 2. In this case, the first antenna group 1 and the second antenna group 2 can be manufactured using similar design modules, and the assembly method of the first circuit board 130 is similar to that of the second circuit board 230, thus reducing costs. Secondly, it should be noted that during assembly, because radio frequency signals are prone to noise and strong interference, in order to design the radio frequency feed lines (usually coaxial cables, with ultra-thin coaxial cables commonly used in laptops) to be further away from or closer to certain circuit modules / or the chassis to comply with testing regulations, the radio frequency feed lines are soldered on the same side, for example, with... Figure 1 In terms of the structure of the arranged active-controlled LTE antennas, the RF feed lines are uniformly soldered to the back side, which results in the back side of the first antenna group 1 being visible from its rear viewpoint (see...). Figure 3 A coaxial cable is fed in, and the back of line group 2 on the second day (visible from the rear view, see...) Figure 8 A coaxial cable is fed in. In other words, on the back side of the first antenna group 1 (see...) Figure 3 Both the main antenna 11 and the secondary antenna 12 are fed in using coaxial cables; on the back of the second antenna group 2 (see...) Figure 8 Both the main complementary antenna 21 and the secondary complementary antenna 22 are fed in using coaxial cables. However, the control signals of the first control unit 13 and the second control unit 23 are low-frequency signals (non-RF signals), so they are not subject to this limitation. Therefore, the first circuit board 130 of the first control unit 13 is on the front of the first antenna group 1, and the second circuit board 230 of the second control unit 23 is on the back of the second antenna group 2, which does not have a significant impact on signal interference.
[0041] Refer to Figure 13The operation frequency band of the main antenna 11 and the main complementary antenna 21 is, for example, 698-960 MHz; at least one of the main antenna 11 and the main complementary antenna 21 is responsible for the operation frequency band of 1557-1610 MHz; the operation frequency band of the main antenna 11 and the auxiliary antenna 12 covers 1710-2620 MHz, 3400-3800 MHz and 5150-5925 MHz; the operation frequency band of the main complementary antenna 21 and the auxiliary complementary antenna 22 covers 1710-2620 MHz, 3400-3800 MHz and 5150-5925 MHz.
[0042] In summary, the active regulation type long term evolution antenna provided by the embodiment of the present application has more available frequency bands than passive antennas, and only needs to use the main antenna and the auxiliary antenna (in combination with the complementary antenna) to simultaneously meet the specifications of the wireless local area network and the wireless wide area network. The radio frequency feeder is configured in a specific manner to reduce the number of antennas and the occupied space of the antennas, and has high industrial application value.
