[0024] Figure 1 A schematic diagram of the structure of the antenna according to the embodiment of the present application is shown. An antenna for a computer device is provided, the antenna comprising a grounding structure 101, an equivalent inductor 104, a first branch 106 and a second branch 107, an antenna feed point 102 is provided at a first position on the upper edge of the grounding structure 101, and a first connector 103 is provided at a second position. Specifically, the grounding structure 101 can be a metal sheet such as copper foil, which is not limited to this. Among them, the shape of the grounding structure 101 can be adapted according to the shape of the antenna bracket, which is not limited to this. The first position of the upper edge of the grounding structure 101 is on the left side of the upper edge, and the second position is on the right side of the upper edge, which is only used as an example.

[0025] Specifically, the electrical signal enters the antenna through the wire feeding from the first position on the upper edge of the ground structure 101. The antenna feed point 102 refers to the physical interface between the antenna and the wireless device, which is used to transmit wireless signals and power, and is usually a joint or connector, connecting the cable or wire between the antenna and the wireless device.

[0026] For example, the antenna is an LDS antenna, which can be understood as an antenna prepared based on the LDS process, wherein the LDS (Laser Direct Structuring) process is a professional laser processing, injection, and electroplating process, the principle of which is to combine ordinary plastic components with antenna and other functions, and is a mature antenna process with very high reliability in mass production. The LDS antenna can be prepared based on the existing public LDS process, and the specific method will not be repeated.

[0027] In this embodiment, the first end of the equivalent inductor 104 is connected to the first connector 103, and the second end is connected to the second connector 105. That is, the two ends of the equivalent inductor 104 are respectively connected to the first connector 103 and the second connector 105 to adjust the antenna impedance matching. The second connector 105 can be a metal wire or a metal sheet, etc., which is not limited.

[0028] The first branch 106 is connected to the second connecting member 105 and the second branch 107 respectively, and the first branch 106 is a rectangular structure, the first part 1071 of the second branch 107 directly connected to the first branch 106 is a rectangular structure, and the second part 1072 is a bent structure. For example, the second connecting member 105 can be a metal sheet, the first branch 106 is a rectangular metal sheet, and the first branch 106 is connected to one end of the second connecting member 105. The first branch 106 and the second branch 107 can be an integrally formed structure, but the structures of the first branch 106 and the second branch 107 are different. Specifically, the first branch 106 is directly connected to the first part 1071 of the second branch 107, and the second part 1072 is a bent structure at the end point of the first part 1071, so that the antenna can maintain a relatively excellent performance while keeping the size of the antenna small.

[0029] In this embodiment, power is fed through the antenna feed point 102, and the input high-frequency current is converted into electromagnetic waves through the antenna and radiated into the air; when receiving, the antenna of the embodiment of the present application can convert electromagnetic waves into high-frequency current. More specifically: the second branch 107 uses a metal wire with a 1 / 4 dielectric wavelength, which is responsible for the electromagnetic wave radiation of the lower frequency band of 2.4G; the first branch 106 is mainly responsible for the electromagnetic wave radiation of the higher frequency band WiFi 5G and 6E band. According to electromagnetic field theory, the transmission wavelength of electromagnetic waves in the medium is calculated as follows: λ=C / f, λ is the wavelength, f is the frequency, and C is the propagation speed of electromagnetic waves in the medium. Among them, C=C0 / √(εr), C0 is the propagation speed of electromagnetic waves in a vacuum, which is equal to the speed of light; εr is the dielectric constant of the medium. The dielectric constant of the antenna bracket described in the embodiment of the present application is 3.1.

[0030] like Figure 2 The antenna provided in this embodiment can be integrally arranged on the antenna bracket 108. The embodiment of the present application cleverly uses the LDS process to design a smaller antenna, which can be integrated with the upper edge of the laptop to ensure the narrow frame appearance of the computer screen and can also well meet the design index requirements of the WLAN antenna.

[0031] In some embodiments of the present application, the antenna feed point 102 is a groove structure, which is designed to facilitate connecting wires and reduce the size.

[0032] In some embodiments of the present application, the first connector 103 includes a third portion parallel to the plane of the ground structure 101 and a fourth portion perpendicular to the plane of the ground structure 101. The fourth portion may be integrally formed with a portion of the equivalent inductor 104, and the connection between the ground structure 101 and the equivalent inductor 104 is achieved through the first connector 103.

[0033] In some embodiments of the present application, the equivalent inductor 104 is a U-shaped structure, and a first end of the U-shaped structure is connected to the fourth portion, and a second end of the U-shaped structure is connected to the second connector 105. Figure 1 The equivalent inductor 104 is a U-shaped structure with an opening on the left side, wherein a first end of an opening of the U-shaped structure is connected to the first connector 103 , and a second end of another opening of the U-shaped structure is connected to the second connector 105 .

[0034] In some embodiments of the present application, the second connector 105 includes a fifth portion parallel to the plane of the grounding structure 101, and a sixth portion perpendicular to the fifth portion, and the second end of the U-shaped structure is connected to the sixth portion. Specifically, the fifth portion is adapted to the antenna feed point 102 on the grounding structure 101, and the wire can be connected through the antenna feed point 102. The sixth portion is perpendicular to the plane where the grounding structure 101 is located, and is connected to the equivalent inductor 104, which is conducive to the antenna formed being installed on the upper edge of the laptop.

[0035] In some embodiments of the present application, the width of the first portion 1071 is smaller than the width of the first branch 106. For example, the width of the first portion 1071 is 1 mm, and the width of the first branch 106 is 2 mm. This is beneficial to improving the performance of the antenna.

[0036] In some embodiments of the present application, the second part 1072 of the second branch 107 includes a wide domain perpendicular to the first part 1071, and a narrow domain parallel to the plane where the first part 1071 is located. Furthermore, the width of the wide domain is greater than the width of the narrow domain, for example, the width of the wide domain is 3 mm, and the width of the narrow domain is 1 mm. In this way, electromagnetic wave radiation supporting WiFi 5G and 6E frequency bands is achieved.

[0037] In some embodiments of the present application, the second branch node 107 is a branch node supporting 2.4G frequency band antenna radiation, and the first branch node 106 is a branch node supporting WiFi 5G and 6E frequency band antenna radiation. Based on the structural characteristics of the first branch node 106 and the second branch node 107, different frequency band antenna radiations are supported respectively.

[0038] In some embodiments of the present application, the grounding structure 101 is a rectangular structure, and the length of the grounding structure 101 is in the range of 15-30 mm, and the width of the grounding structure 101 is in the range of 5-10 mm. Preferably, the length of the grounding structure 101 is 20 mm, and the width of the grounding structure 101 is 8 mm. In this way, when the antenna is small in size, the performance advantage can still be met.

[0039] Figure 3 Another schematic diagram of the dimensions of the antenna according to the embodiment of the present application is shown, and the dimensions are shown in Table 1:

[0042] Specifically, Table 1 shows the size of the antenna designed in the embodiment of the present application, which is only used as an example and does not constitute a limitation on the specific solution. It can be seen that the size of the antenna is small (the width W1 can be 2.5 mm), which is suitable for the upper edge of the laptop screen.

[0043] The antenna of the embodiment of the present application is designed to be integrated with the frame of the laptop screen, which can effectively improve the antenna radiation performance; in addition, the antenna of the embodiment of the present application is small in size, so it can save costs. The most important point is that the antenna of the embodiment of the present application can realize an antenna design suitable for the upper edge of the laptop screen, which can effectively improve the appearance of the product and is the future trend of laptop appearance design.

[0044] The antenna of the embodiment of the present application is tested for return loss characteristics, which are better than -9dB in all frequency bands (2.4GHZ&5G&WIFI6E bands), meeting the design indicators of SPEC (Standard Performance Evaluation Corporation, Standard Performance Evaluation Organization). SPEC requires better than -6dB in all frequency bands. The antenna radiation gain characteristics of the embodiment of the present application are better than 5.5dB in the peak gain of all frequency bands where the WLAN antenna works (2.4GHZ&5G&WIFI 6E bands), meeting the design requirements. In addition, the antenna of the embodiment of the present application has excellent radiation directivity characteristics. Therefore, the antenna of the embodiment of the present application has excellent characteristics.
