Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Please refer to Figure 1As shown, this application embodiment provides a 5G antenna, including: a substrate 10, which may be a PCB board, and a radiating component disposed on the substrate 10. The radiating component includes a first radiator, a second radiator, a third radiator, and a fourth radiator. The second, third, and fourth radiators are all connected to the first radiator. The lengths of the first, second, third, and fourth radiators are different, and the lengths of the first, second, third, and fourth radiators are all quarter wavelengths of their respective control frequency bands.

[0026] Different radiators are used to achieve different frequency bands of the antenna. This application has four radiators, each of which can control different frequency bands of the antenna. The second, third and fourth radiators are all connected to the first radiator. The four radiators have different lengths in the vertical direction, which correspond to a quarter wavelength of the frequency band controlled by the antenna. Therefore, the combination of the four radiators can achieve the performance requirements of the 5G full frequency band.

[0027] For example Figure 2 As shown, the stretched length of the first radiator (length L0 of the first radiating arm 110 + length of the straightened S-shaped radiating arm 112 + length of the extension arm 111) is 84 mm, the lateral width is 0.5 mm, and it controls the low-frequency band of 600 MHz to 960 MHz.

[0028] The second radiator has a length L2 of 8 mm and a lateral width of 0.5 mm, and controls the mid-to-high frequency band of 3300 MHz to 4200 MHz.

[0029] The third radiator has a length L3 of 6 mm and a lateral width of 0.5 mm, and controls the ultra-high frequency band of 4200 MHz to 6000 MHz.

[0030] The fourth radiator has a length L4 of 26 mm and a lateral width of 0.5 mm, and controls the intermediate frequency band of 1710 MHz to 2690 MHz.

[0031] It is evident that the higher the frequency band controlled by each radiator, the shorter the length of the radiator.

[0032] Specifically, the first radiator includes a vertically arranged first radiating arm 110 and an S-shaped radiating arm 112 laterally connected to the top of the first radiating arm 110. The S-shaped radiating arm 112 includes multiple bends 113 arranged vertically. The S-shaped radiating arm 112 includes a first end 114 connected to the top of the first radiating arm 110 and a second end 115 facing the bottom of the first radiating arm 110. The second end 115 is also connected to an extension arm 111, which is parallel to the first radiating arm 110 and extends vertically toward the bottom of the first radiating arm 110.

[0033] The first radiator has a relatively complex shape, including a first radiating arm 110, an S-shaped radiating arm 112, and an extension arm 111. The first radiating arm 110 is arranged vertically, forming a vertical strip. The S-shaped radiating arm 112 is presented with a serpentine trace, with its first end 114 connected to the top of the first radiating arm 110 and its second end 115 connected to the extension arm 111. The first end 114 and the second end 115 are connected by multiple bends 113 to form an S-shape. The extension arm 111 starts from the second end 115 of the S-shaped radiating arm 112 and extends towards the bottom of the first radiating arm 110 until it connects to the conductive via 16 at the bottom of the substrate 10. Furthermore, the extension arm 111 forms an irregular structure from the second end 115 toward the conductive via 16, with a slender upper part, a widened middle part, and a slender lower part.

[0034] The irregular structure formed by the first radiator allows the second, third, and fourth radiators to connect with the first radiator, respectively.

[0035] The second radiator includes a second radiating arm 120 connected to the second end 115 of the S-shaped radiating arm 112 and parallel to the extension arm 111. The second radiating arm 120 extends vertically toward the bottom end of the first radiating arm 110.

[0036] The third radiator includes a third radiating arm 130, which is arranged parallel to the second radiating arm 120. The third radiating arm 130 is located on the side of the second radiating arm 120 away from the extension arm 111, and extends from the bottom end of the first radiating arm 110 toward the second end 115 of the S-shaped radiating arm 112.

[0037] The second radiating arm 120 and the third radiating arm 130 each form a relatively short strip structure. The upper end of the second radiating arm 120 is connected to the second end 115 of the S-shaped radiating arm 112, and the lower end extends toward the bottom of the substrate 10. The lower end of the third radiating arm 130 is connected to the widened position in the middle of the extension arm 111, and the upper end extends toward the top of the substrate 10.

[0038] The fourth radiator includes a fourth radiating arm 140, which is arranged parallel to the third radiating arm 130. The fourth radiating arm 140 is located on the side of the third radiating arm 130 away from the second radiating arm 120, and extends from the bottom end of the first radiating arm 110 toward the second end 115 of the S-shaped radiating arm 112.

[0039] The fourth radiating arm 140 forms a slightly elongated strip structure. The extension ends of the third radiating arm 130 and the fourth radiating arm 140 toward the S-shaped radiating arm 112 are both vertically spaced from the second end 115 of the S-shaped radiating arm 112. The extension end of the second radiating arm 120 toward the bottom of the substrate 10 is also vertically spaced from the extension arm 111.

[0040] In the horizontal direction, the first radiating arm 110, the extension arm 111, the second radiating arm 120, the third radiating arm 130, and the fourth radiating arm 140 are arranged in parallel and at intervals. That is, a gap is formed between the first radiating arm 110 and the extension arm 111, and a gap is also formed between the extension arm 111 and the second radiating arm 120, and so on, in order to avoid interference between the radiating arms.

[0041] In addition, an electronic component 15 is also provided on the first radiator to eliminate the influence of the fourth harmonic resonance and to act as a filter. The position of the electronic component 15 needs to be placed on the first radiating arm 110 (the radiating arm that controls the low frequency). The specific position is not fixed and only needs to be convenient for placing the pads. Different positions require different capacitors to match the filtering. For example, the electronic component 15 can use a 0402 capacitor with a capacitance ≤2pF. In this application, the electronic component 15 uses a 0.75pF capacitor to eliminate the influence of the antenna's low-frequency 900MHz fourth harmonic resonance (3.6GHz±100MHz) on the antenna performance and improve the efficiency near the fourth harmonic.

[0042] like Figure 3 As shown, a connector 17 is also provided at the bottom end of the first radiator on the substrate 10. The connector 17 is connected to the first radiator through a conductive via 16 for connecting external devices. The entire assembly is packaged in a housing 10A to form an antenna product.

[0043] The extension arm 111 of the first radiator is connected to a conductive via 16, and a connector 17 is connected through the conductive via 16 so that the antenna and external devices can be connected. The width D1 of the conductive via 16 is ≤2mm.

[0044] The conductive via 16 can also be tin-plated. Tin has good conductivity, so tin plating can improve the conductivity of the conductive via 16. When connected to external devices, the continuity and uniformity of the tin plating layer can also ensure the reliability of signal transmission. In addition, tin plating gives the conductive via 16 good corrosion resistance, which can extend the service life of the antenna.

[0045] The 5G antenna provided in this application embodiment is small in size, making it convenient to assemble in small-sized communication devices. For example... Figure 1The dimensions of the medium antenna are: length L≤47mm, width D2≤5mm, substrate 10 width D3≤5mm, and substrate 10 thickness≤1mm. The antenna boasts high performance, covering the entire 5G frequency band and effectively meeting the performance requirements of 5G; it also features low cost, helping customers save on antenna expenses.

[0046] Figure 4 The efficiency diagram of the 5G antenna of this application is shown. The antenna covers the entire 5G frequency band. The antenna efficiency is relatively high when the antenna is in the frequency bands of 600MHz~960MHz, 1710MHz~2690MHz, 3300MHz~4200MHz, and 4200MHz~6000MHz.

[0047] Based on this, on the other hand, this application also discloses an electronic device, including any of the above-mentioned 5G antennas. The electronic device can be a computer, mobile phone, etc., including the above-mentioned 5G antenna.

[0048] This electronic device includes the same structure and beneficial effects as the 5G antenna in the foregoing embodiments. The structure and beneficial effects of the 5G antenna have been described in detail in the foregoing embodiments and will not be repeated here.

[0049] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
