[0002] Wi-Fi antenna is a core device for realizing Wi-Fi network transmission, and its main functions include signal transmission, signal enhancement and multi-directionality. Wi-Fi antenna can be divided into two categories: omnidirectional antenna and directional antenna. Omnidirectional antenna provides 360-degree signal coverage and is suitable for occasions requiring extensive coverage. Directional antenna concentrates signals in a specific direction and is suitable for long-distance point-to-point or point-to-multipoint Wi-Fi network. Among them, the PCB board is an important component of the WiFi antenna, and the microstrip line on the PCB board is responsible for transmitting wireless signals from the wireless module to the antenna, which is the key channel for signal transmission.

[0034] Reference Figs. 1 to 4 The utility model discloses a built -in antenna, including pole cover 100, interface end 200 and terminal 300, pole cover 100 with interface end 200 articulates, be equipped with PCB board 400 in pole cover 100, interface end 200 is connected with terminal 300 through cable 500, pole cover 100 includes connecting portion 120 and body portion 110, the connecting portion 120 with the body portion 110 junction forms step portion,

[0035] The body portion 110 is in sheet shape.

[0036] The built-in antenna of the embodiment is a high-frequency WiFi antenna, with a frequency band of 2.4G or 5G. The pole cover 100 is in gray U shape, including a body portion 110 and a connecting portion 120. The body portion 110 is in flat sheet structure, and the PCB board 400 is installed in the body portion 110. In the horizontal direction, the PCB board 400 is installed at the bottom of the pole cover 100, but in the vertical direction, the distance from the PCB board 400 to the edge of the plate is 3.40 mm. The design purpose is as follows: first, it can provide additional buffer protection under vibration or impact to prevent the PCB board 400 from being directly stressed and reduce the risk of physical damage; second, the 3.40 mm spacing provides a gap that is beneficial to air flow, helps the electronic components on the PCB board 400 to dissipate heat, and ensures the stable operation of the circuit under high load or high temperature environment; finally, the distance design can provide a certain shielding effect for the PCB board 400, reduce the influence of external electromagnetic interference on the circuit, and improve the electromagnetic compatibility of the equipment.

[0037] Correspondingly, the connecting portion 120 and the body portion 110 are connected to form a step portion. The step portion design increases the hierarchical structure of the pole cover 100. When the antenna falls or is impacted by external force, the external force directly acts on the connecting portion 120, which plays a buffering role for the PCB board 400 installed in the pole cover 100, reduces the impact of external force on the PCB board 400, and achieves the purpose of protecting the PCB board 400. On the other hand, the step portion design also enhances the structural strength of the antenna.

[0038] The cable 500 is plated with a tin layer 600 at both ends in the length direction.

[0039] The cable 500 is connected with the interface end 200 and the terminal 300 at both ends in the length direction. In this embodiment, the connection points of the cable 500 with the interface end 200 and the terminal 300 are plated with a tin layer 600. The tin layer 600 forms a layer of good conductive interface on the contact surface, which helps to reduce the contact resistance and improve the conductive efficiency. At the same time, it also reduces the loss of high-frequency signals at the connection point, improves the connection reliability, and ensures the stable transmission of high-frequency signals.

[0040] The length of the cable 500 is 125 mm.

[0041] The cable 500 is a white low-loss cable.

[0042] The cable 500 is a gray low-loss cable.

[0043] In this embodiment, the length of the cable 500 is 125 mm, and it is a white or gray low-loss cable. The length of the 125 mm cable 500 can provide appropriate length for effective signal transmission in most application scenarios, while avoiding the problems of signal attenuation, delay or interference caused by too long cable 500. The low-loss cable 500 is designed to reduce energy loss during signal transmission, maintain high signal quality and improve device efficiency. In addition, the low-loss cable 500 often comes with better electromagnetic shielding performance, which can effectively reduce electromagnetic interference inside and around the cable 500, and maintain the integrity and clarity of the signal. In addition, the white and gray colors help to better reflect heat, and absorb less heat than dark colors. This plays a positive role in preventing the cable 500 from overheating to protect the internal signal line and insulation layer. Light-colored cable 500 can provide relatively better weather resistance in some application scenarios, such as outdoor or high-temperature environments, because light-colored cables absorb less heat and are less affected by changes in environmental temperature.

[0044] The terminal 300 is provided with a conductive layer.

[0045] Correspondingly, the terminal 300 is plated with a conductive layer. In this scheme, the conductive layer is made of gold. Gold has high corrosion resistance and oxidation resistance, and is not easily oxidized by oxygen or moisture in the air like silver or copper. Therefore, it can maintain the stability of electrical connection for a long time. Because gold is not easily worn or corroded, the terminal 300 can still maintain good contact and electrical performance after long-term use, thereby improving the overall reliability and service life of the device.

[0046] The connection part 120 is provided with an open slot, the interface end 200 is connected with the rod sleeve 100 through a rivet, and the interface end 200 rotates along the trajectory of the open slot.

[0047] The interface end 200 can rotate 0-90 degrees relative to the rod sleeve 100.

[0048] The rivet is fixed between the rod sleeve 100 and the interface end 200 as a rotating shaft, so that the interface end 200 can rotate around the rivet to adjust the direction, and the open slot serves as a guide track to limit the rotation range to 0-90 degrees; the user can manually adjust the direction of the interface end 200, so that the antenna can receive or send signals in different directions, thereby optimizing the signal strength and quality.

[0049] The body part 110 is provided with heat dissipation fins.

[0050] The body part 110 is uniformly provided with a plurality of heat dissipation fins in the length direction, and the main purpose of the heat dissipation fins is to improve the heat dissipation efficiency of the antenna; the heat dissipation fins can effectively dissipate the heat generated during the operation of the antenna by increasing the heat dissipation area, thereby reducing the hotspot temperature and ensuring the normal operation of the system; the design of the heat dissipation fins realizes the integration of the functions of the antenna and the radiator; the design of the heat dissipation fins has a positive influence on the electromagnetic performance of the antenna; the additional heat dissipation fins do not reduce the radiation performance of the antenna, but rather enhance the radiation intensity of the original microstrip patch antenna; through effective heat dissipation, it is helpful to prevent the deterioration of the performance of the device caused by excessively high temperature, thereby improving the reliability and stability of the entire wireless communication system.

[0051] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application; any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the present application specification and drawings, is also included in the patent protection range of the present application.
