摘要
针对5G大规模天线当前系统架构及技术方案,提出了一种宽频小型化辐射单元,从理论上分析了辐射单元宽频化和小型化实现的可行性;并通过HFSS仿真设计了一种小型化双频辐射单元来进一步验证,辐射单元是利用双层辐射面相互耦合产生两个谐振点来实现双频特性,同时采用耦合馈电方式进一步扩展带宽,辐射单元载体是基于印刷电路结构,对地高度仅1/8波长,尺寸小,设计成本低,可制造性强,设计灵活度大。
According to the current system architecture and technical solution of 5G large-scale antenna,a broadband and miniaturized radiating element is proposed,where the feasibility of realizing broadband and miniaturization for the radiating element is theoretically analyzed.Then a miniaturized dual-frequency radiating element is designed through HFSS simulation for further verification.Specifically,the dual-frequency characteristics of the radiating element are realized by utilizing two resonance points generated by mutual coupling of double-layer radiating surfaces,and the bandwidth is expanded via a coupling feeding mode.The radiating element carrier is based on a printed circuit structure with the height to the ground of merely 1/8 wavelength and the advantages of small size,low design cost,strong manufacturability and flexible design.
