However, the size and installation position of components such as antennas and cameras seriously limit the narrow frame design of electronic devices. Taking a laptop as an example, if the antenna is set at the system end, the antenna is easily interfered during the operation of the system end, which will seriously affect the efficiency of the antenna and the quality of the received and transmitted signals, resulting in large signal noise received and transmitted by the antenna. Therefore, the antenna is usually set at the upper frame of the display end, which requires the upper frame of the display end to have sufficient width, which greatly limits the narrow frame design of the display end.

[0030] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figure 1 As shown, an embodiment of the present application provides an electronic device, which includes a display unit 1 and a system unit 2 connected to each other. The display unit 1 and the system unit 2 can be hinged to each other. In this case, the electronic device can be, for example, a laptop computer. Of course, the electronic device is not limited to a laptop computer, but can also be other types of electronic devices. The display unit 1 and the system unit 2 are not limited to being hinged to each other, and the display unit 1 and the system unit 2 can also be detachably connected to each other. Figure 2As shown, the display unit 1 may include a display screen 3 and a circuit board 4 connected to and overlapped with the display screen 3. For example, the display unit 1 may include a housing, the display screen 3 may be arranged on one side of the housing, and a cavity is formed between the display screen 3 and the other side of the housing, and the circuit board 4 may be installed in the cavity and arranged parallel to the display screen 3. The circuit board 4 includes a display portion, which may be used to control the display screen 3 to output display content, and one end of the display portion close to the system unit 2 extends outward to form an extension portion 5, and at least one antenna is provided on the extension portion 5, and the antenna is connected to the system unit 2. For example, the extension portion 5 may be provided with a first antenna 6 and a second antenna 7.

[0032] In the electronic device adopting the above structure, the antenna is arranged on the display unit 1, which can reduce the electromagnetic interference to the antenna during the operation of the system unit 2, so that the antenna has better performance and lower noise; and the antenna is arranged on the circuit board 4 at a position close to the system unit 2, which does not affect the design of the upper frame and the two side frames of the display unit 1, which is beneficial to realize the narrow frame design of the upper frame and the two side frames of the display unit 1, thereby improving the aesthetics and market competitiveness of the electronic device.

[0033] In some embodiments, the display unit and the system unit 2 are connected via a coaxial line to transmit display signals, and the antenna is connected to the system unit 2 via the coaxial line. Compared with the signal transmission line of the antenna being separately provided, the wiring relationship between the display unit 1 and the system unit 2 can be simplified, thereby reducing the difficulty of assembling and producing the electronic device. In the specific implementation process, the structure of the coaxial line can be improved so that the coaxial line can transmit antenna signals, such as the coaxial line can include a display signal transmission line group and an antenna signal transmission line group; the existing coaxial line can also be used to transmit both display signals and antenna signals.

[0034] In some embodiments, the antenna and the coaxial line are connected through a microstrip line provided on the extension portion 5. The microstrip line is small in size, light in weight, has a wide operating frequency band, has high reliability and low manufacturing cost, and is beneficial to improving production efficiency and reducing production costs. In a preferred embodiment, the microstrip line may include: a first conductive wire segment 10 and a second conductive wire segment (not shown in the figure), one end of the first conductive wire segment 10 is connected to the antenna, one end of the second conductive wire segment is connected to the other end of the first conductive wire segment 10, and the other end of the second conductive wire segment is connected to the coaxial line, the first conductive wire segment 10 is laid along the surface of the extension portion 5, and the second conductive wire segment is passed through the interior of the extension portion 5. In this way, the line loss of the microstrip line can be reduced. Figure 4 As shown, after testing, the line loss of the antenna of the electronic device at 2.4GHz frequency is -1.0DB, and the line loss at 5GHz frequency is -1.1dB, and the line loss in the working frequency band is relatively small.

[0035] In some embodiments, the extension portion 5 is symmetrically provided with a first antenna 6 and a second antenna 7. By providing the first antenna 6 and the second antenna 7, the overall average gain of the antenna of the electronic device can be improved, and the overall ability of the antenna to transmit and receive signals can be enhanced. In a specific implementation, the extension portion 5 may have a first end and a second end relative to each other, the first antenna 6 and the second antenna 7 are located at the first end and the second end, respectively, the first antenna 6 is connected to the coaxial line through the first microstrip line 8, and the second antenna 7 is connected to the coaxial line through the second microstrip line 9. In this way, interference between the first antenna 6 and the second antenna 7 can be avoided. In a preferred embodiment, the first wire segment 10 of the first microstrip line 8 and the first wire segment 10 of the second microstrip line 9 extend toward each other, and the second wire segment of the first microstrip line 8 and the second wire segment of the second microstrip line 9 are arranged in parallel in the middle of the extension portion 5.

The second antenna unit is located on one side of the opening of the first antenna unit, and the second antenna unit includes a fourth branch 14 parallel to the third branch 13, one end of the fourth branch 14 extends toward the third branch 13 to form a fifth branch 15, the fifth branch 15 extends from the U-shaped opening between the first branch 11 and the second branch 12 and is connected to the third branch 13, and the other end of the fourth branch 14 extends in a direction away from the third branch 13 to form a sixth branch 16. In the specific implementation process, the fifth branch 15 and the sixth branch 16 can be perpendicular to the fourth branch 14. Furthermore, the sixth branch 16 and the first branch 11 can be located on the same straight line. In addition, the first branch 11 can also extend toward the direction close to the second branch 12 to form the seventh branch 17.

[0037] like Figure 5 As shown, the first antenna 6 and the second antenna 7 of the electronic device have obvious antenna modes in the 2.4 GHz and 5 GHz frequency bands, such as Figure 6 As shown, the 3D average gain of the first antenna 6 and the second antenna 7 can meet the standard requirements, such as Figure 7 As shown, the radiation fields of the first antenna 6 and the second antenna 7 at 2.4 GHz and 5.6 GHz are close to spherical, indicating that the first antenna 6 and the second antenna 7 have strong signal receiving and sending capabilities at 360 degrees.
