The market urgently needs an intelligent device that takes into account performance, portability, and cost, and the microcomputer has emerged as the times require.

[0003] Different from laptops and tablet computers that pursue lightness and thinness, in order to pursue a smaller volume, microcomputers tend to stack components to better utilize the vertical space. This makes the component density inside the microcomputer greater, and the distance between the stray interference sources generated in the motherboard and the antenna is closer, which will reduce the receiving sensitivity of the entire machine's radio frequency system, thereby affecting the effect of wireless communication. Summary of the Invention

[0028] Modern office scenarios cannot do without the support of computers. In recent years, the demand for mobile office among office workers has been increasing day by day. However, common desktop hosts have problems such as large volume and heavy weight, and are not suitable for carrying around, nor for flexible office scenarios. Thin and light laptops are usually expensive and have limited performance, while tablets are more inclined to entertainment scenarios. The market urgently needs an intelligent device that combines performance, portability, and cost, and the microcomputer has emerged as the times require.

[0029] Different from laptops and tablets that pursue thinness and lightness, in order to pursue a smaller volume, microcomputers tend to stack components to better utilize the vertical space. This makes the component density inside the microcomputer greater, and the distance between the stray interference sources generated in the motherboard and the antenna is closer, which will reduce the receiving sensitivity of the overall radio frequency system of the microcomputer, thereby affecting the effect of wireless communication.

[0030] To solve the above problems, the present invention proposes a WLAN antenna structure 10, which includes an antenna unit 1. The antenna unit 1 includes a dielectric substrate 11, an antenna floor 12, and radiation branches 13. The radiation branches 13 are connected to the antenna floor 12, and the radiation branches 13 and the antenna floor 12 are arranged on the same side of the dielectric substrate 11. The antenna unit 1 is arranged at an interval and isolated from the motherboard 30 in the microcomputer 100 and is connected through a feeder line.

[0031] The technical solution of the present invention proposes a WLAN antenna structure 10, which includes an antenna unit 1 isolated from the main board 30. The antenna unit 1 includes a dielectric substrate 11, an antenna floor 12, and radiation branches 13. The radiation branches 13 are connected to the antenna floor 12, and both are located on the same side of the dielectric substrate 11. This design enables the WLAN antenna structure 10 to be compactly integrated into the microcomputer 100. The WLAN antenna unit 1 is isolated from the main board 30 and connected by a feeder. This isolation design can effectively reduce the electromagnetic interference between the antenna and the main board 30, ensuring that the antenna can stably receive and transmit signals. The connection method of the feeder ensures efficient signal transmission while avoiding signal loss during transmission. The dielectric substrate 11 provides physical support and also helps to ensure the electrical performance of the antenna, such as resonance frequency and bandwidth. The antenna floor 12, as part of the signal reflection, works together with the radiation branches 13 to enhance the radiation efficiency of the antenna. Overall, this structural design optimizes the space utilization while ensuring the antenna performance, reduces the interference of the main board 30 to the antenna, and ensures the normal operation of the antenna, making it suitable for various electronic devices, especially in devices with limited space such as the microcomputer 100.

[0032] In an optional embodiment, to further improve the isolation effect of the WLAN antenna structure 10, the WLAN antenna structure 10 further includes a reflector 2. The reflector 2 is disposed between the main board 30 and the antenna unit 1 and shields the antenna unit 1. A reflecting surface 21 is formed on the side of the reflector 2 facing the antenna unit 1, and the reflecting surface 21 is used to reflect the energy of the antenna unit 1. This reflection design can effectively enhance the radiation directivity of the WLAN antenna structure 10, concentrate more energy in a specific direction, and thus improve the antenna gain. At the same time, the presence of the reflector 2 further isolates the antenna unit 1 from the main board 30, reduces electromagnetic interference, and improves the stability and reliability of the WLAN antenna structure 10. The shape and material of the reflecting surface 21 have a direct impact on the reflection effect. Usually, a material with good conductivity is selected to make the reflecting surface 21 to ensure the reflection efficiency. In this embodiment, the material of the reflector 2 is copper, and the surface of the reflecting surface 21 is relatively smooth, which can improve the reflection effect of the reflecting surface 21 on the radiation signal of the antenna unit 1.

[0033] In an alternative embodiment, for facilitating the installation and connection of the antenna element 1 and the reflector 2, the WLAN antenna structure 10 further includes a first support member 3 and a second support member 4. The antenna element 1 is connected to the first support member 3, and the reflector 2 is connected to the second support member 4. A support portion is stacked and bonded with the second support plate to form an integral structure. This support design not only provides stable physical support for the antenna element 1 and the reflector 2, but also enhances the integrity and stability of the WLAN antenna structure 10 through stacking and bonding. The material selection and size design of the first support member 3 and the second support member 4 can be specifically selected according to factors such as the weight of the antenna element 1, the working environment, and electromagnetic compatibility. In this embodiment, the materials of the first support member 3 and the second support member 4 are block-shaped insulating foam. The insulating foam has good conductivity and elasticity, can effectively shield electromagnetic interference, and at the same time provides stable support for the antenna element 1 and the reflector 2. The conductivity of the insulating foam enables it to form a good electrical connection with the antenna element 1 and the reflector 2, further enhancing the electromagnetic shielding effect. In addition, the elastic characteristics of the insulating foam can absorb a certain amount of mechanical vibration and impact, protect the WLAN antenna structure 10 from the influence of external physical factors, and contribute to improving the stability of the WLAN antenna structure 10.

[0034] In an alternative embodiment, the antenna element 1 is bent and wrapped around the first support member 3, and the reflector 2 is wrapped around the second support member 4. And the reflector 2 is bent to form a flange on the side close to the antenna element 1. The antenna element 1 being bent and wrapped around the first support member 3 can effectively protect the antenna element 1 from external physical damage and also helps to optimize the radiation characteristics of the antenna. The reflector 2 is wrapped around the second support member 4 and forms a flange through bending. The design of the flange can further enhance the reflection effect, reflect more energy back to the radiation direction of the antenna, thereby increasing the gain of the antenna. In addition, the flange can also play a certain shielding role, reducing the electromagnetic coupling between the antenna element 1 and the surrounding environment and improving the anti-interference ability of the WLAN antenna structure 10.

[0035] In an alternative embodiment, for the convenience of realizing the overall installation of the WLAN antenna structure 10, the WLAN antenna structure 10 further includes a mounting shell 5. The mounting shell 5 is formed with a receiving groove, and the first support member 3 and the second support member 4 are clamped in the receiving groove. The design of the mounting shell 5 not only provides additional protection for the WLAN antenna structure 10, but also ensures the precise installation and fixation of the WLAN antenna structure 10 in the device. The design of the receiving groove matches the dimensions and shapes of the first support member 3 and the second support member 4 to ensure the stability and reliability of the clamping connection. Specifically, the mounting shell 5 can be a plastic shell or a metal shell. The WLAN antenna structure 10 is integrally arranged in the mounting shell 5. In this way, when the WLAN antenna structure 10 is modularly installed on the microcomputer 100, only the mounting shell 5 needs to be integrally connected and installed and then the feeder connection is carried out, which improves the installation convenience and also facilitates the overall disassembly, installation and maintenance of the subsequent WLAN antenna structure 10.

[0036] The present invention also provides a microcomputer 100, which includes a WLAN antenna structure 10, a housing 20 and a main board 30. The housing 20 has opposite first and second ends. The main board 30 is arranged in the installation cavity at the first end, and the second end is formed with an installation groove 201. The WLAN antenna structure 10 is clamped in the installation groove 201. The specific structure of the WLAN antenna structure 10 refers to the above embodiment. Since the microcomputer 100 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Integrating the antenna structure into the housing 20 of the microcomputer 100 not only saves space, but also improves the installation efficiency and stability of the WLAN antenna structure 10. The design of the housing 20 helps to optimize the layout and directivity of the antenna to ensure that the WLAN antenna structure 10 can effectively receive and transmit signals. The isolation design between the main board 30 and the antenna can reduce electromagnetic interference and improve the stability and reliability of the entire system. In addition, the material and structure design of the housing 20 also have an important impact on the performance of the antenna.

[0037] Optionally, the second end of the housing 20 / the housing 20 is made of metal to enable signal isolation between the two WLAN antenna structures 10. The metal housing 20 can effectively shield electromagnetic interference and provide a relatively independent electromagnetic environment for the WLAN antenna structure 10, thereby improving the stability and reliability of the signal. Signal isolation is particularly important for multi-antenna systems, especially in MIMO applications. Good isolation can reduce the mutual coupling effect between the WLAN antenna structures 10 and improve the overall performance of the system. The metal material of the housing 20 can improve its shielding efficiency. In addition, the metal housing 20 can also provide certain mechanical strength and heat dissipation performance, further improving the durability and stability of the microcomputer 100. In this embodiment, the entire housing 20 is made of metal, and the upper cover above the housing 20 is made of plastic, so that the shielding effect of the metal housing can be reduced in one direction for the WLAN antenna structure 10, and it helps to improve the directivity of the WLAN antenna structure 10. The housing 20 around the two mounting grooves 201 is made of metal to improve the isolation effect between the two WLAN antenna structures 10 and between the WLAN antenna structure 10 and the main board 30, which helps to improve the receiving sensitivity of the WLAN antenna structure 10.

[0038] In an optional embodiment, both the WLAN antenna structure 10 and the mounting groove 201 include two, and one WLAN antenna structure 10 is clamped in one mounting groove 201. This dual-antenna design can achieve spatial diversity and improve the signal receiving and transmitting performance. Especially in a multipath propagation environment, it can effectively reduce the influence of signal fading. The independent installation and layout of the two antenna structures can optimize the directivity and coverage of the antenna, and at the same time, it also helps to improve the anti-interference ability of the system. The design of the mounting groove 201 enables each WLAN antenna structure 10 to be stably clamped therein, and the two WLAN antenna structures 10 are spaced apart to avoid mutual interference and achieve the best signal transmission effect. In addition, the dual-antenna design can also support MIMO (multiple input multiple output) technology to further improve the data transmission rate and system capacity.

[0039] In an optional embodiment, the two WLAN antenna structures 10 have the same / different sizes. This design flexibility enables the antenna structures to adapt to different application requirements and device layouts. When the two antenna structures have the same size, symmetric signal coverage and uniform gain distribution can be achieved, which is suitable for devices and application scenarios with a symmetric layout. When the sizes are different, the performance of each antenna can be optimized according to the specific structure and signal requirements of the device. The two WLAN antenna structures 10 can be used as the main antenna and the diversity antenna respectively. The main antenna is the main signal receiving and transmitting unit, responsible for communicating with remote devices. It has a high gain and directivity and can effectively receive and transmit signals. The diversity antenna is used to receive signals from different paths. Through diversity reception techniques (such as space diversity, frequency diversity, polarization diversity, etc.), the multipath fading and interference of signals can be effectively reduced. The diversity antenna receives multiple independent signal copies and combines them at the receiving end (such as maximum ratio combining, equal gain combining, etc.), which can significantly improve the stability and reliability of the signals. This can not only optimize and improve the signal radiation range of the WLAN antenna structure 10, but also help improve the overall anti-interference ability of the WLAN antenna structure 10. Especially in the microcomputer 100 with limited space, by reasonably designing the size and layout of the WLAN antenna structure 10, better signal isolation and performance optimization can be achieved.

[0040] The following specifically describes an embodiment of the microcomputer 100 and the WLAN antenna structure 10 inside it in this solution:

[0041] Figure 1 It is a top view of the antenna unit 1 in the unfolded state proposed in this solution. The antenna unit 1 includes radiation branches 13, a dielectric substrate 11, and an antenna floor 12. Both the radiation branches 13 and the antenna floor 12 are made of metal and are printed on the upper surface of the dielectric substrate 11. In addition, a solder mask material is covered above the radiation branches 13 and the antenna floor 12 to prevent short circuits caused by contact with the metal housing 20. The shape of the radiation branches 13 is a U-shaped folded branch, and there is a feeding point on the lower side of the branch. In the WiFi 2.4G band, the antenna operates in the loop antenna mode, and in the WiFi 5G band, the antenna operates in the monopole antenna and slot antenna modes.

[0042] Figure 2This is the installation procedure for the WLAN antenna structure 10 of this design. The WLAN antenna structure 10 further includes a first support member 3, a reflector 2, and a second support member 4. The antenna unit 1 is bent and arranged to wrap around the periphery of the first support member 3. The reflector 2 is wrapped around the periphery of the first support member 3, and the reflector 2 is bent towards the side close to the antenna unit 1 to form a baffle, further improving the isolation effect on the antenna unit 1. Moreover, the side of the reflector 2 facing the antenna unit 1 has a relatively smooth and flat reflecting surface 21. The reflecting surface 21 can reflect the radiation energy in the backward direction of the antenna to improve the radiation efficiency of the antenna. In addition, compared with directly using the housing 20 of the microcomputer 100 for reflection, the forming difficulty of processing a smooth surface on the reflector 2 is undoubtedly lower. That is to say, this helps to reduce the processing and forming difficulty and convenience, and helps to ensure the stability of the radiation direction and phase of the electromagnetic wave after reflection. Specifically, in this embodiment, the reflector 2 is a dielectric substrate 11, and the reflecting surface 21 is formed by printing copper foil on the dielectric substrate 11. In other embodiments, a metal structure such as a copper plate or an aluminum plate can also be integrally processed into the reflector 2 to achieve a similar effect, and specific selection can be made according to actual needs. By connecting the antenna unit 1 to the first support member 3, connecting the reflector 2 to the second support member 4, and stacking the first support member 3 and the second support member 4 vertically and bonding them integrally. In this embodiment, both the first support member 3 and the second support member 4 are block-shaped insulating foams, and the overall WLAN antenna structure 10 after bonding and forming also presents a block structure, which is convenient for realizing the overall installation of the WLAN antenna structure 10.

[0043] Figure 3 This is a schematic diagram of the installation structure of the WLAN antenna structure 10 in the microcomputer 100 in this solution. The microcomputer includes a housing 20, a main board 30, and the WLAN antenna structure 10. The housing 20 has opposite first and second ends in the up-down direction. The main board 30 is installed in the installation cavity at the lower first end. An installation groove 201 is formed at the upper second end. The WLAN antenna structure 10 is snap-fitted and installed in the installation groove 201. And in this embodiment, there are two WLAN antenna structures 10 with different sizes, and the two WLAN antenna structures 10 are spaced apart and used as the main antenna and the diversity antenna respectively to improve the signal radiation range and the overall anti-interference ability of the WLAN antenna structure 10. During installation, the main antenna and the diversity antenna are respectively assembled and then installed in the installation groove 201, and the wires are led out from the holes reserved in the installation groove 201 and connected to the RF module of the main board 30. Please refer to Figure 3, in this embodiment, the bottom plate 40 under the housing 20 and the main board 30 is made of metal, and the cover plate 50 above the two WLAN antenna structures 10 is made of plastic. In this way, both the sides and the bottom of the WLAN antenna structures 10 are metal, enabling good isolation between the two WLAN antenna structures 10 and between the WLAN antenna structures 10 and the main board 30, which helps improve the anti-channel fading ability of the entire antenna diversity system. The connection between the WLAN antenna structures 10 and the main board 30 is achieved only through the feeder, and the interference signals generated by the main board 30 are greatly reduced to ensure that the antenna can have good receiving sensitivity. The protective cover plate 50 on the top of the WLAN antenna structures 10 uses a plastic structure, which can reduce the signal shielding of the WLAN antenna structures 10 and helps improve the directivity of the antenna and ensure the intensity of the radiated signal.

[0044] Figure 4 And Figure 5 respectively show the actual test results of the reflection coefficients of the main antenna and the diversity antenna ports in this solution. Among them, Figure 3 the larger-sized WLAN antenna structure 10 on the right side in the figure is the main antenna, and the smaller-sized WLAN antenna structure 10 on the left side is the diversity antenna. The -10dB impedance bandwidths of the two frequency bands of the antenna are 2.40 - 2.52 GHz and 4.91 - 7.24 GHz respectively, which can completely cover the 2.4 GHz, 5 GHz, and 6 GHz frequency bands of WiFi1 - WiFi7, realizing the expansion of the antenna bandwidth under the condition of being wrapped by the metal housing 20 and with a small antenna installation space.

[0045] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
