[0015] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the following combines with the drawings and example, and further detailed description is made to the utility model.
[0016] As Figure 1 The utility model discloses a 5G CPE antenna of low hertz frequency band, including PCB board 1, grounding sheet 2, be equipped with high frequency radiator 3 and low frequency radiator 4 on PCB board 1, the one end of high frequency radiator 3 and low frequency radiator 4 is oppositely arranged in the middle part of PCB board 1, and the other end of high frequency radiator 3 and low frequency radiator 4 respectively extends to the both sides of PCB board 1, and high frequency radiator 3 and low frequency radiator 4 are all equipped with feeding point 5 on the opposite position, and the position of high frequency radiator 3 is equipped with grounding installation hole 6, and grounding sheet 2 is connected on grounding installation hole 6.
[0017] The 5G CPE antenna of low hertz frequency band further comprises a radio frequency wire 7, and one end of the radio frequency wire 7 is connected with the feeding points 5 of the high frequency radiator 3 and the low frequency radiator 4 respectively.
[0018] The structure uses PCB board 1, radio frequency wire 7 and grounding sheet 2 to realize 5G CPE product 700Mhz~2700Mhz.The grounding sheet 2 is preferably a steel sheet, and the design and structure of the steel sheet are for meeting the appearance of the whole machine and better assembly.The area of the antenna is increased after the steel sheet is connected to the mainboard, so that the interference killing capacity of the antenna is improved, and the performance is better.Compared with the conventional PCB full-band antenna, the steel sheet is connected to the mainboard on the PCB board 1, so that the area of the antenna is increased, the interference killing capacity of the antenna is improved, and the performance is better.The reference ground of the antenna is greater than one wavelength after the steel sheet is connected to the mainboard, so that the performance is better, and the low-frequency performance of the antenna with a large area is better than that of the antenna with a small area.
[0019] The left side of PCB board 1 uses a high-frequency radiator 3, and the right side uses a low-frequency radiator 4, which makes it easier to adjust the antenna impedance. The grounding mounting hole 6 is placed at the high-frequency radiator 3 to optimize antenna performance.
[0020] A grounding coating 8 is provided around the grounding mounting hole 6, and the grounding plate 2 is in contact with the grounding coating 8. The high-frequency radiator 3 and the low-frequency radiator 4 are made of copper foil, while the grounding coating 8 is made of copper-free material. Copper foil has high conductivity and corrosion resistance, and using copper foil as the material for the radiator can ensure the stability of the antenna signal. The grounding coating 8 is made of copper-free conductive material, which, while achieving grounding by connecting with the steel plate, does not affect the radiation effect between the high-frequency radiator 3 and the low-frequency radiator 4.
[0021] like Figure 2 As shown, the grounding plate 2 includes a grounding pin 21, a grounding extension plate 22, and a grounding fixing plate 23. The grounding pin 21 and the grounding fixing plate 23 are respectively connected to both ends of the grounding extension plate 22. The grounding pin 21 is inserted into the grounding mounting hole 6 and fixed. The grounding fixing plate 23 is used to fix the antenna equipment. The antenna is set above the main board of the equipment. The grounding fixing plate 23 has screw holes. When one end of the steel plate is connected to the main board of the equipment, the steel plate can be fixed to the main board of the equipment by tightening screws, thereby fixing the entire antenna. The grounding extension plate 22 can adapt to the distance between the installation position of the PCB board 1 and the main board position, so that the steel plate can be connected to the PCB board 1 and the main board of the equipment respectively. The steel plate is provided with two grounding pins 21, and the position of the high-frequency radiator 3 is provided with two grounding mounting holes 6. The grounding pin 21 is inserted into the grounding mounting hole 6 for fixed connection. The fixing method can be a conductive connection method such as welding.
[0022] The high-frequency radiator 3 extends to one end of the PCB board 1 and then adopts a folded-back routing structure. The folded-back routing structure of the high-frequency radiator 3 is used to control the frequency impedance of the antenna in the high-frequency range of 1710MHz~2690MHz.
[0023] The low-frequency radiator 4 has a multi-segment bent trace structure on one side of the PCB board 1. The multi-segment bent trace structure of the low-frequency radiator 4 is used to couple the high frequency 1710MHz~2170MHz, and also to allow the low-frequency radiator 4 to be fully deployed within this area.
[0024] In a conventional PCB board 1, the efficiency of a 700MHz antenna can reach 35%. However, in this invention, after the PCB board 1 is grounded to the device motherboard via a steel sheet, the antenna itself references the ground of the device motherboard, which is equivalent to increasing the antenna's area. Therefore, the passive efficiency from 700MHz to 960MHz can be achieved at around 50%. Furthermore, with a larger reference ground, the anti-interference capability is also very strong; general interference will not affect the low-frequency TIS of our antenna.
[0025] The utility model discloses a PCB board 1 + radio frequency cable line + steel sheet, through the lock screw connection antenna mainboard or radiator whole machine, the utility model discloses a product more than the steel sheet grounding of conventional antenna product, so greatly strengthened the interference killing capacity of antenna itself, and the overall promotion of antenna passive performance, after the steel sheet grounding, the passive efficiency performance of 700Mhz ~ 960Mhz will be higher than conventional antenna under the same size of PCB area.
[0026] The 5G CPE antenna of the low hertz frequency band is simple and easy to operate during production line assembly, the product antenna has good radiation performance, strong interference killing capacity, high stability and good OTA performance consistency during antenna whole machine testing.
[0027] The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, on the premise of not departing from the concept of the utility model, a number of simple deductions or substitutions can be made, which should be regarded as belonging to the protection scope of the utility model.
