An antenna radiation unit applied to a 5G system

Abstract

The invention discloses an antenna radiation unit applied to a 5G system, and relates to the 5G technical field. The antenna radiation unit comprises an upper layer dielectric body, a lower layer dielectric body, a radiation patch, a parasitic patch, a plurality of feeding probes, a metal ground plane and a feeding network. The upper layer dielectric body is coaxially arranged at the upper end ofthe lower layer dielectric body, the lower end of the lower layer dielectric body is connected with a metal grounding plate, a plurality of feeding probes are axially symmetrically arranged on the outer side of the lower layer dielectric body, and the feeding probes are positioned between the metal grounding plate and the radiation patch and are kept direct current disconnected from the metal grounding plate; The feeding network is arranged at the lower end of the metal ground plane and feeds the feeding probe through the pins. The parasitic patch is arranged on the upper surface of the uppermedium body, and the radiation patch is arranged on the upper surface of the lower medium body. The radiating element body can be formed integrally, has high machining precision, simple structure andis easy to be assembled in the later stage. At the same time, it can achieve bipolarization, broadband, high gain, high cross-polarization discrimination and other electrical characteristics.

Description

technical field [0001] The present invention relates to the field of 5G technology, in particular to an antenna radiation unit applied to a 5G system. Background technique [0002] With the rapid development of the mobile Internet and the emergence of more and more smart devices, there will be great communications in various fields such as ultra-high-definition video, virtual reality, augmented reality, smart wear, smart home, smart meter reading, and smart transportation. need. The network rate, network capacity, number of terminal connections, and air interface delay of the 4G mobile communication system can no longer meet the needs of the market and technological evolution. In the future, wider bandwidth, higher speed, lower power consumption, shorter delay and faster connection Dense and more secure 5G technology. [0003] As one of the key technologies of 5G, large-scale antenna technology can well solve the shortcomings of 4G technology. A large-scale antenna array ...
