Embodiment Construction

[0032] The main body of a 5G large-scale array antenna provided by the present invention includes a radiation unit part, a power division feed network part, an interlayer support plate part, a coupling calibration network part, a spacer part, and a T / R component part; wherein, the radiation unit part consists of It consists of N sub-arrays (N can be 8, 16, 32, 64, 128), and the leading channels are connected to the corresponding T / R components.

[0033] The dual-polarized radiating oscillator of the radiating unit part is directly connected with the power dividing and feeding network part. The part of the power distribution feed network is a single-layer board in the form of a microstrip. The coupling calibration network part is a multi-layer board in the form of stripline with signal shielding function. The interlayer support plate is partly hollowed out, and its material can be FR4 plate or metal plate.

[0034] In order to better understand the above-mentioned technical s...

Abstract

The invention belongs to the technical field of mobile communication and discloses a 5G large-scale array antenna. The sandwich support plate part is located between a power distribution feed networkpart and a coupling calibration network part. The sandwich support plate part is a local hollow structure. The power distribution feed network part and the coupling calibration network part are connected by signals after welding. The radiating element is composed of several dual-polarized radiating oscillators which are fixedly connected with the power dividing and feeding network. A plurality ofdual-polarized radiators form a sub-array, and each sub-array leads to two dual-polarized channels, which are partially connected with the T/R module. The 5G large-scale array antenna provided by theinvention can still have excellent amplitude consistency and phase consistency under complex signal environment.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a large-scale dense array antenna related to a 5G mobile communication system. Background technique [0002] With the continuous development of my country's mobile communication technology, the research on the fifth-generation mobile communication system (5G) has entered a substantive stage, and major operators have started 5G coverage pilots in some cities in China. As one of the key core technologies of the 5G mobile communication system, large-scale array antenna technology, the current system has higher and higher requirements for the overall antenna. It can even be said that the improvement and improvement of large-scale array antenna technology has become a key factor in 5G wireless communication. A crucial support point for development. The key to the requirements for 5G large-scale array antennas is that they can support 3D beamforming and more powerful MIMO...
