[0051] To illustrate the technical solutions described in this application, specific embodiments are provided below, showing only the parts related to the embodiments of this application.

[0052] like Figure 1 and Figure 2 As shown, this application provides an LTE and WiFi combined antenna 1, including a satellite message and positioning antenna 30, an antenna board 10, a base 40, and multiple support components 20. The LTE and WiFi combined antenna 1 can be a PCB printed structure.

[0053] In some embodiments, the satellite message and positioning antenna 30 can be mounted on a base 40, and multiple support members 20 are arranged around the satellite message and positioning antenna 30 on the base 40. One end of each support member 20 is connected to the base 40, and the other end can be connected to the antenna plate 10 to fix the antenna plate 10 above the satellite message and positioning antenna 30.

[0054] In some embodiments, such as Figure 3 As shown, the antenna board 10 may include a substrate 100, an LTE trace 210, a WiFi trace 320, and multiple mounting holes 400 for corresponding connection with the support member 20. The substrate 100 can support the LTE trace 210 and the WiFi trace 320. The LTE trace 210 can be used for antenna resonance in the LTE band, and the WiFi trace 320 can be used for antenna resonance in the WiFi band. The mounting holes 400 can be correspondingly provided with the support member 20, that is, the number of mounting holes 400 can be the same as the number of support members 20. The antenna board 10 can be connected to the support member 20 through the mounting holes 400 to fix the antenna board 10. The antenna board 10 can be made of FR4 material, with a thickness of 1.0 mm and a diameter of 132 mm.

[0055] In some embodiments, the LTE trace 210 may include an LTE antenna, and the WiFi trace 320 may include a WiFi antenna. The LTE antenna and the WiFi antenna may be printed on the substrate 100 by etching and photolithography, or integrally formed on the substrate 100 by copper plating.

[0056] In some embodiments, the antenna plate 10 may further include a rectangular open area 500, which may be formed by hollowing out the central region of the antenna plate 10 and located directly above the satellite message and positioning antenna 30. The rectangular open area 500 may be used to transmit satellite message and positioning antenna signals.

[0057] In some embodiments, the antenna board 10 may also include multiple edge chamfers 600, which can be used for overall structure installation, i.e., installation of subsequent antenna products.

[0058] It should be noted that the traces in this application can refer to copper-clad traces, that is, the LTE trace section 210 and the WiFi trace section 320 in this application can both be made by copper-clad integration.

[0059] In some embodiments, the LTE routing section 210 may include an outer ring routing area 200 and a ground reference area 201. The ground reference area 201 may be arranged around a rectangular void area 500, and the outer ring routing area 200 may be arranged around the ground reference area 201. The outer ring routing area 200 may include a first analog power supply port F1, a rectangular routing area 202, a first concave routing area 204, a second concave routing area 207, a square frame routing area 209, a first short circuit point S1, a second short circuit point S2, and a plurality of chamfered routing areas. The square frame routing area 209 includes a plurality of frame traces, and two adjacent frame traces of the square frame routing area 209 are connected through chamfered routing areas.

[0060] In some embodiments, one end of the first concave routing area 204 can be connected to one end of the first chamfered routing area 205, the other end of the first concave routing area 204 can be connected to one end of the second chamfered routing area 203, one end of the second concave routing area 207 can be connected to one end of the third chamfered routing area 208, the other end of the second concave routing area 207 can be connected to one end of the fourth chamfered routing area 206, the other end of the first chamfered routing area 205 can be connected to the other end of the third chamfered routing area 208, and the other end of the second chamfered routing area 203 can be connected to the other end of the fourth chamfered routing area 206. Specifically, the routing areas can be connected by border routing. For example, one end of the first concave routing area 204 can be connected to one end of the first chamfered routing area 205 by border routing. Correspondingly, the aforementioned adjacent routing areas can all be connected by border routing and can be integrally formed by copper plating, which will not be elaborated here.

[0061] In some embodiments, the first analog power supply port F1 can be located inside the outer ring routing area 200, that is, in the area between the outer ring routing area 200 and the ground reference area 201. Specifically, the first analog power supply port F1 can be located inside the frame routing between the second chamfered routing area 203 and the fourth chamfered routing area 206.

[0062] In some embodiments, the rectangular trace area 202 may be located near the first analog power supply port F1 and outside the outer ring trace area 200. Specifically, the rectangular trace area 202 may be located outside the frame trace between the second chamfered trace area 203 and the fourth chamfered trace area 206.

[0063] In some embodiments, the first short-circuit point S1 and the second short-circuit point S2 can both be located inside the outer ring routing area 200. Specifically, the first short-circuit point S1 and the second short-circuit point S2 can both be located inside the frame routing between the first chamfered routing area 205 and the third chamfered routing area 208, and are connected to both the outer ring routing area 200 and the ground reference area 201.

[0064] In some embodiments, the WiFi wiring section 320 may include a second analog power supply port F2, an upper resonant arm 300 and a lower resonant arm 310. One end of the second analog power supply port F2 may be connected to the upper resonant arm 300, and the other end of the second analog power supply port F2 may be connected to the lower resonant arm 310.

[0065] In some embodiments, the upper resonant arm 300 may include a first rectangular feed area 301 and a first rhombic drain area 302, and the lower resonant arm 310 may include a second rectangular feed area 303 and a second rhombic drain area 304. One end of the second analog feed port F2 may be connected to one end of the first rectangular feed area 301, and the other end of the first rectangular feed area 301 may be connected to the first rhombic drain area 302. The other end of the second analog feed port F2 may be connected to one end of the second rectangular feed area 303, and the other end of the second rectangular feed area 303 may be connected to the second rhombic drain area 304. Both the first rhombic drain area 302 and the second rhombic drain area 304 may include through holes. By setting the first rhombic drain area 302 and the second rhombic drain area 304, the obstruction of the satellite signal under the board by the copper foil can be further reduced. The upper resonant arm 300 and the lower resonant arm 310 are two dipole resonant arms. The first rhomboid leakage area 302 and the second rhomboid leakage area 304 are symmetrically arranged with respect to the second analog power supply port F2.

[0066] In some embodiments, the first analog power supply port F1 and the second analog power supply port F2 can be used to simulate a coaxial cable (not shown in the figure). One side of each analog power supply port can represent connecting the inner core of the coaxial cable, and the other side can represent connecting the outer core of the coaxial cable. In actual use, the first analog power supply port F1 and the second analog power supply port F2 can be connected by welding.

[0067] In some embodiments, the LTE and WiFi combined antenna 1 may include a coaxial cable (not shown), one end of which may be connected to a first analog feed port F1, and the other end of which may be connected to a second analog feed port F2. A through-hole may be provided on the antenna plate 10. One end of the coaxial cable may be soldered to the first analog feed port F1 on a first surface of the antenna plate 10, and then the other end of the coaxial cable may pass through the through-hole to the second surface of the antenna plate 10 and be soldered to the second analog feed port F2.

[0068] In some embodiments, such as Figure 3As shown, the first concave trace area 204 and the second concave trace area 207 can both be formed by hollowing out a semicircle from a rectangular trace area, that is, by hollowing out a semicircular structure from a rectangular structure. On the one hand, this can be used to avoid the mounting hole 400 to avoid interference; on the other hand, it can increase the path length of the resonant current flowing along the outer ring, thereby reducing the antenna size to a certain extent. Each chamfered trace area can be used to avoid the corresponding edge chamfer 600.

[0069] In some embodiments, the first short-circuit point S1 and the second short-circuit point S2 can be used to connect the outer ring trace area 200 to the ground reference area 201 to form a loop antenna circuit. Specifically, through the first short-circuit point S1 and the second short-circuit point S2, the outer ring trace area 200 can be divided into an upper resonant ring and a lower resonant ring. The upper resonant ring can be formed by the rectangular trace area 202 surrounded by the second chamfered trace area 203, the first concave trace area 204, the second chamfered trace area 203, the first short-circuit point S1, and the border traces between them. The lower resonant ring can be formed by the rectangular trace area 202 surrounded by the fourth chamfered trace area 206, the second concave trace area 207, the third chamfered trace area 208, the second short-circuit point S2, and the border traces between them. Figure 3 As shown, GP1 and GP2 can represent the gaps between the upper and lower resonant rings and the ground reference layer, respectively. The S-parameters of the upper and lower resonant rings can be optimized by adjusting the gaps, so that the antenna has good efficiency, while also affecting the resonant frequency to some extent. Figure 4 The figure shown is a schematic diagram of the S-parameters of the LTE and WiFi combined antenna 1 of this application under different GP1 conditions.

[0070] Generally, under the same dielectric conditions, each current flow length corresponds to a resonant frequency f0. The higher the frequency f0, the shorter the path of the resonant current and the shorter the antenna resonant arm; the lower the frequency f0, the longer the path of the resonant current and the longer the antenna resonant arm. Furthermore, the LTE antenna section uses a loop antenna design principle. For a loop antenna, its circumference C0 corresponds to the wavelength λ0 at the fundamental frequency f0, i.e., f0 = speed of light c / λ0. In addition, when the loop antenna has a ground reference area 201, it will generate two more monopole antenna frequencies f1 and f2 at 0.5λ0 and 1.5λ0, respectively, on top of f0. Since f1 and f2 are monopole antennas, their resonance is 1 / 4 wavelength, therefore f1 = speed of light c / (4*0.5λ0) and f2 = speed of light c / (4*1.5λ0). In this application, the upper resonant ring has a large circumference and the lower resonant ring has a small circumference, each generating three resonant frequencies, each with a certain bandwidth. The frequencies and bandwidths generated by the upper large resonant ring and the lower resonant ring are superimposed on each other.

[0071] like Figure 5As shown, the LTE wiring section 210 of this application generates a total of 7 resonant points in 0.74GHz, 0.83GHz, 1.07GHz, 1.58GHz, 1.86GHz, 2.18GHz and 2.55GHz. Each resonant point has a certain bandwidth, and finally meets S11<-6dB in the range of 0.675GHz to 1.144GHz and 1.480GHz to 2.940GHz, forming a good resonance and covering the requirements of the full LTE frequency band range of 0.698GHz to 0.960GHz and 1.710GHz to 2.690GHz.

[0072] The second analog feed port F2 of this application can be used to represent a coaxial line, wherein the inner core of the coaxial line can be welded to the first rectangular feed area 301, and the outer core can be welded to the second rectangular feed area 303. When an electromagnetic signal is fed in through the coaxial line, a high-frequency current flows along the periphery of the upper and lower resonant arms. The current path of the upper and lower resonant arms is approximately 1 / 4 of the waveguide wavelength of the target design frequency. Figure 6 As shown, the WiFi wiring section 320 of this application resonates at 2.44GHz. This resonance has a certain bandwidth and satisfies S11<-10dB in the range of 2.287GHz to 2.646GHz, which meets the range requirement of 2.4GHz to 2.5GHz for the 2.4G WiFi band.

[0073] In some embodiments, the inner core of the coaxial cable can be connected to the first rectangular feed area 301, and the outer core of the coaxial cable can be connected to the second rectangular feed area 303.

[0075] Regarding the resonant point of 0.74GHz, the resonance at 0.74GHz is mainly achieved by the upper and lower resonant rings together. Specifically, Figure 7 The diagram shows the current distribution at a certain phase of 0.74 GHz.

Specifically, Figure 19 The diagram shows the current distribution at a certain phase of 1.86 GHz. The radio frequency signal is transmitted from the first analog feed port F1 to the rectangular trace area 202, and then flows to the upper and lower resonant rings, eventually achieving resonance near this frequency point. Figure 20 The image shows the far-field 3D radiation pattern at 1.86 GHz. Figure 21 The image shows the EH surface lobe pattern at 1.86 GHz.

[0080] Regarding the resonant point of 2.18 GHz, the resonance at 2.18 GHz is mainly achieved by the upper and lower resonant rings together.
