[0018] The embodiment of the present application provides an LTE IoT antenna and integrates a work area on the surface of a PCB board, so that the copper foil determines the position of the connection with the work area on the PCB board according to the installation position between the IoT antenna and the IoT device, and designs the copper foil according to the shape of the connection area of ​​the IoT antenna. After the copper foil 4 is electrically connected to the IoT antenna, the two can be adapted to ensure that one end of the antenna can be completely covered by the copper foil, so as to avoid the copper foil being exposed from the surface of the PCB board and being affected by the metal around the PCB board, thereby achieving full coverage of the 4G frequency band, reducing the influence of the metal on the antenna signal transmission, and reducing the antenna's dependence on the installation environment. Thus, better transmission efficiency and convenient installation methods are achieved than the 4G IoT antenna on the market, and because the copper foil is designed at a special position on the surface of the PCB board, the space size of the antenna installation can be reduced to solve the problem of the connection between the base of the existing IoT smart device antenna and the copper foil on the PCB board. Because the antenna position is mostly close to the metal around the PCB board, and the copper foil completely covers the surroundings of the connection between the antenna and the PCB board, when the antenna sends and receives signals, it will be interfered by the metal, resulting in the weakening of the 4G partial frequency band signal, thereby causing the problem of abnormal communication of the IoT device.

[0019] Embodiment 1:

[0020] LTE IoT antennas, such as Figure 1-Figure 2As shown, it includes a mounting structure supporting its communication, the mounting structure includes a PCB board 1 and a copper foil 4, the copper foil 4 is arranged on the surface of one side of the PCB board 1, and forms a working area 2 capable of transmitting and receiving radio signals, and the copper foil 4 is arranged in a contour with the connection area of ​​the Internet of Things antenna;

[0021] Among them, by profiling the copper foil 4 and the IoT antenna connection area, when the IoT antenna connection area is connected to the copper foil 4, the two can be adapted to ensure that one end of the antenna can be completely covered by the copper foil 4, and the copper foil 4 is prevented from being exposed from the surface of the PCB board 1 and affected by the surrounding metal;

[0022] Secondly, by setting the PCB board 1 inside the IoT device, after connecting one end of the IoT antenna to the copper foil 4, the other end of the IoT antenna is extended from the inside of the IoT device. In the process of designing the copper foil 4, the position of the IoT antenna compared to the PCB board 1 is referred to. After the copper foil 4 is set on the surface of the PCB board 1 to form the working area 2, the antenna can be adapted to the installation position of the IoT device housing, so as to reduce the space occupied by the IoT antenna and the PCB board 1 inside the IoT device.

[0023] Furthermore, in order to facilitate the fixing of the PCB board 1 and the IoT device, the antenna connected to the PCB board 1 is extended from the inside of the IoT device housing, such as Figure 1 As shown, positioning holes 3 are processed at the four corners of the PCB board 1. By passing bolts through the positioning holes 3 and threadedly connected with the IoT device, the PCB board 1 can be fixed to the IoT device, and the surface of the PCB board 1 away from the copper foil 4 is fitted with the fixed position area to ensure the stability of the installation of the PCB board 1;

[0024] At the same time, in order to prevent the bolts passing through the positioning hole 3 from causing signal interference to the copper foil 4, thereby interfering with the signal transmission work of the IoT antenna, such as Figure 1 As shown, the areas where the copper foil 4 covers the four positioning holes 3 are processed with insulating rings. By arranging the insulating rings coaxially with the positioning holes 3, when the insulating glue is hot-melt connected inside the insulating rings and the insulating glue and the copper foil 4 are separated from each other, direct contact between the bolts passing through the positioning holes 3 and the copper foil 4 can be avoided.

[0025] This utility model LTE Internet of Things antenna:

[0026] By arranging the copper foil 4 on the surface of the PCB board 1, the copper foil 4 is distributed to form a working area that can well transmit and receive radio signals, so that the connection position of the Internet of Things antenna and the copper foil 4 on the PCB board 1 can be determined according to the installation position between the Internet of Things antenna and the Internet of Things device, and the copper foil 4 is designed according to the shape of the connection area of ​​the Internet of Things antenna. After the copper foil 4 is electrically connected to the Internet of Things antenna, the two can be adapted to ensure that one end of the antenna can be completely covered by the copper foil 4, and the copper foil 4 is prevented from being exposed from the surface of the PCB board 1 and affected by the metal around the PCB board 1. Compared with the 4G IOT antenna on the market, full coverage of the 4G frequency band is achieved at a low cost, the influence of metal on antenna signal transmission is reduced, and the antenna is less dependent on the installation environment. In addition, due to the special position design of the copper foil 4 on the surface of the PCB board 1, the space size of the antenna installation can be reduced;

[0027] At the same time, when the PCB board 1 is fixed inside the IoT device with bolts, the insulating glue hot-melted on the PCB board 1 can be filled in the isolation ring on the copper foil 4 to avoid direct contact between the bolts passing through the positioning hole 3 and the copper foil 4. This can assist in the setting of the specific position of the copper foil 4 and the contour design of the connection area with the IoT antenna, further reducing the influence of the metal around the PCB board 1 on the antenna signal transmission.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
