[0023] Reference Figure 1-4 The utility model provides a vehicle-mounted 5G high-isolation combination antenna, including an antenna shell 1, wherein an antenna assembly 2 is embedded at four inner corners of the antenna shell 1; a circular mounting groove 3 is provided around the outer side of the antenna shell 1; a sliding groove 4 is provided at four positions on the upper end of the antenna shell 1; an isolation assembly 5 is provided at four positions on the upper end of the antenna shell 1, and there are 4 isolation assemblies 5 in total, and the isolation assembly 5 is located on the outer side of the antenna assembly 2. The four isolation assemblies 5 are vertically arranged in sequence to form a rectangular space. When the antenna assembly 2 is used, in order to improve the operation during use, an isolation shell 501 is installed on the outer side of the antenna assembly 2, so that when the antenna assembly 2 is in operation, the signals emitted by other antenna assemblies 2 are prevented from interfering with the antenna assembly 2, thereby improving the isolation of the antenna during use.

[0024] It should be noted that in the process of use, in order to improve the high-speed operation of the network and improve the smoothness of network use, people set up multiple receiving elements and antennas inside the antenna, and the elements will cause interference during operation, which will affect the operation of the antenna and will also be transmitted to the human body. The radiation will directly affect human health.

[0025] As a further implementation scheme of the above technical solution: Figure 1-4As shown, the isolation component 5 includes an isolation shell 501; a tensioning plate 502 is provided at one end of the inner side of the isolation shell 501 close to the antenna component 2; a mounting shaft 503 is provided at one end of the isolation shell 501 away from the antenna shell 1, and a through hole 504 is provided at one end of the mounting shaft 503 away from the antenna shell 1; a fixing component 6 is embedded in the inner side of the mounting shaft 503; a tensioning component 7 is provided at one end of the fixing component 6 close to the center of the antenna shell 1. During installation, taking the isolation component 5 on the front right as an example, the isolation shell 501 is inserted from the front to the rear side of the antenna. In the shell 1, when inserting, the left end of the isolation shell 501 is aligned with the sliding groove 4 opened at this position, and then manually pushed to the rear end until the through hole 504 provided on the installation axis 503 in the isolation shell 501 coincides with the installation groove 3 in the antenna shell 1, and then the fixing component 6 is manually inserted into the isolation shell 501 from right to left until the fixing component 6 penetrates the isolation shell 501 and contacts the tensioning component 7 in the installation groove 3 provided in the antenna shell 1. The isolation component 5 provided on the outside of the antenna shell 1 can isolate the interference and laying of the antenna component 2 during operation, thereby improving the isolation degree during use.

[0026] As a further implementation scheme of the above technical solution: Figure 1-4 As shown, the fixing component 6 includes a fixing shaft 601; a countersunk hole 602 is provided at the right end of the fixing shaft 601, and the countersunk hole 602 is 5 mm deep; a threaded hole 603 is provided at the right end of the fixing shaft 601, and the threaded hole 603 has a thread pitch of M4X1.5; a screw 604 is connected to the inner thread of the fixing shaft 601, and the screw 604 passes through the fixing shaft 601. When the isolation component 5 needs to be disassembled, the sleeve required by the screw 604 can be inserted from right to left into the countersunk hole 602, and the sleeve is stuck in the nut of the screw 604 and manually rotated. After the screw 604 is turned out one section, the nut of the screw 604 can be clamped by tweezers or the like and pulled to the right, and the fixing shaft 601 is pulled out of the isolation shell 501 by pulling force.

[0027] As a further implementation scheme of the above technical solution: Figure 4As shown, the tensioning assembly 7 includes a fixing block 701; a groove 702 is provided at one end of the fixing block 701 away from the center of the antenna housing 1, and the groove 702 is arranged in a circular shape, a nail 703 is fixedly connected in the groove 702 arranged at one end of the fixing block 701 away from the center of the antenna housing 1, and the nails 703 are distributed in the fixing block 701 in an arc array, the nails 703 penetrate the fixing shaft 601, and the nails 703 and the fixing shaft 601 are in an interference fit, when the fixing shaft 601 is inserted into the isolation housing The fixing shaft 601 is slightly hit with a small hammer to embed the nail 703 at the right end of the fixing block 701 into the fixing shaft 601, so that the outer diameter of the left end of the fixing shaft 601 becomes larger due to the multiple nails 703 embedded inside, and the fixing shaft 601 is tightly fitted with the antenna housing 1 in an interference fit state, thereby improving the stability of the fixing shaft 601 on the inside, making it easier for the isolation component 5 to be fixed in the antenna housing 1.

[0028] As a further implementation scheme of the above technical solution: Figure 3-4 As shown, the tensioning plate 502 is made of a plate made of soft silicone material, and the tensioning plate 502 fits tightly with the antenna shell 1. The tensioning plate 502 is arranged in a triangular shape. When inserted into the isolation shell 501, the front end is easily inserted according to the shape, and contacts with the rear end of the tensioning plate 502 after being inserted for a while. Due to the material and shape of the tensioning plate 502, the further the isolation shell 501 is pushed backward, the greater the thickness of the contact between the antenna shell 1 and the tensioning plate 502, thereby reducing the space between the isolation shell 501 and the antenna shell 1. When pushing the rearmost end, the front end of the tensioning plate 502 is deformed under the action of the internal space, thereby increasing the damping and friction when the isolation shell 501 and the antenna shell 1 are pushed.
