摘要
Sub 6 GHz的3~5GHz的频段被作为5G基站天线的主频段进行使用,然而随着频段的升高,天线辐射范围的缩小及辐射功率衰减加大等问题不容忽视。文中设计了一款基于磁电偶极子的基站双极化天线单元,单元尺寸为0.50λ×0.50λ×0.23λ(中心频率为4 GHz),其在3~5 GHz内VSWR<1.5。天线单元相对带宽(VSWR<2)达到63.5%(2.9~5.6 GHz),其增益在3~5 GHz内大于7.8 dBi,单元的峰值增益达到了11 dBi左右,并实现了2×2的平面阵列仿真,天线阵列的峰值增益达到了17.2 dBi。由HFSS软件仿真可知,设计的天线不仅结构简单、紧凑,且覆盖带宽较大,能满足5G基站天线的需求。
The main frequency band(3~5 GHz)of Sub 6 GHz is taken as the main frequency band of 5G base station antennas.However,as the frequency band increases,the reduction of antenna radiation range and the increase of radiation power attenuation are obvious and cannot be ignored.A base station dual⁃polarized antenna unit based on the magneto⁃electric(ME)dipole is designed in this paper.Its unit size is 0.50λ×0.50λ×0.23λ(the center frequency is 4 GHz).When it is within 3~5 GHz,its VSWR<1.5,its relative bandwidth(VSWR<2)reaches 63.5%(2.9~5.6 GHz),its gain(within 3~5 GHz)>7.8 dBi,and its peak gain reaches about 11 dBi.In addition,the simulation of a 2×2 planar array is realized,and the peak gain of the antenna array reaches 17.2 dBi.It can be seen from thesimulation software HFSS that the designed antenna is not only simple and compact,but also covers a large bandwidth,so it can meet the requirements of 5G base station antenna.
