Embodiment Construction

[0031] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0032] A 5G large-scale array antenna proposed by the present invention includes a reflector, a PCB board, a dense radiation array, and a blind-mating RF connector. The PCB board is printed with a feed circuit and a calibration circuit, of which there are: N×M A dense radiation array composed of dual-polarized oscillators; at least 2×N and at most 2×N×M directional couplers are connected through power stages to form a multi-level calibration network. The multi-level calibration network includes sub-calibration circuits and connection sub-calibration A lumped calibration circuit of the circuit; at least 2×N and at most 2×N×M blind-mating RF connectors, the blind-mating RF connectors, dual-polarized oscillators and the feed network together form a radio frequency channel. Wherein, N≥2 and is an even number, and M≥2. The blind-mating radio ...

Abstract

The invention provides a 5G large-scale array antenna which comprises a dense radiation array, a reflecting plate, a PCB and a blind-inserting type radio-frequency connector. The PCB is printed by a calibration network and a feed network; and the dense radiation array is composed of a plurality of double-polarization oscillators fixed on the reflecting plate, and each double-polarization oscillator comprises a radiation unit and a feed piece; and decoupling devices are arranged among the radiation units; and an isolation resistor is designed in each stage power division port of the feed network and the multi-stage calibration network. The decoupling devices designed for the dense radiation array ensure the direction graphs of all the radio frequency channels are consistent. The multi-stage calibration network adopts a plurality of beneficial technologies to ensure that the amplitude-phases of all the radio frequency ports are consistent; and therefore, the 5-G large-scale array antenna disclosed by the invention can achieve a good service and broadcasting direction graphs through the beam forming technology, making the antenna very suitable to be applied to a 5G large-scale antenna system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the key technology of the 5th generation mobile communication, 5G large-scale array antenna. Background technique [0002] The rapid development of the mobile communication system has gone through 4 generations, and is currently developing to the 5th generation. The main feature of the first-generation cellular mobile analog communication system (1G) is voice communication, the second-generation cellular mobile digital communication system (2G) can perform digital signal transmission (voice + text), and improve data throughput. The third-generation cellular mobile Communication system (3G), the minimum transmission speed is 384K, the maximum is 2M, and the bandwidth can reach more than 5MHz. It can not only transmit voice, but also support multimedia data communication (multimedia) such as web browsing and file download. The fourth generation of cellular mobile communication...
