The radiating unit for 5G antenna provided by the embodiment of the present invention achieves a high degree of aggregation of the previously separated radiating unit, power distribution feed network, and decoupling device, and the selection of the dielectric substrate has the advantage of light weight, making the whole The size of the machine antenna is significantly reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a radiation unit used for a 5G antenna. Background technique [0002] With the continuous development of mobile communication technology, the fifth-generation mobile communication system (5G) has entered the trial commercial stage of a large-scale test network, and major operators have started 5G coverage trials in some cities in China. From the perspective of operators' needs, 5G equipment needs to be miniaturized and lightweight for practical deployment. 5G equipment is an AAU equipment that integrates a large-scale array antenna. This requirement for miniaturization and light weight will inevitably become a requirement for 5G large-scale array antennas. [0003] The number of radiation units used in 5G large-scale array antennas is mostly more than 96 dual-polarization units, and the number of radiation units far exceeds that of 4G conventional base stati...

AI Technical Summary

Problems solved by technology

Conventionally designed radiation units mainly use metal die-casting vibrator and PCB vibrator; metal die-casting vibrator has a disadvantage in weight and does not meet the requirements of lightweight; PCB vibrator is composed of multiple parts, and its assembly and welding are complicated.

Moreover, for 5G antennas, the radiation unit needs to be cascaded with the power distribution feed network to achieve amplitude and phase excitation; while the current conventional 5G antenna design uses the radiation unit and the power distribution feed network PCB are independent Components, the cascade installation between the two is complicated and time-consuming, the number of solder joints is large, and the consistency is poor, which is not conducive to mass automated production and difficult to adapt to the needs of future 5G antennas
