摘　　要：为满足第五代移动通信技术(5th Generation Mobile Communication Technology,5G)对高速数据速率的要求,提出一种新型5G全频段客户前置设备(Customer Premise Equipment,CPE)内置高增益天线。采用顶部开槽单极子与对称分支结构地面设计,实现了紧凑型5G高增益全向天线,通过匹配微带线获得良好阻抗带宽。仿真和实测结果表明,该天线具有良好的全向辐射特性,频段可覆盖N7(2500~2570 MHz)、N38(2570~2620 MHz)、N41(2496~2690 MHz)、N48(3550~3700 MHz)、N77(3300~4200 MHz)、N78(3300~3800 MHz)和N79(4400~5000 MHz)等5个通信频段。其中,低频段效率为60%,高频段效率达到70%,测试结果与仿真结果基本一致。A new 5G full-band Customer Premise Equipment(CPE)built-in high-gain antenna is proposed to meet the requirements of the 5th Generation Mobile Communication Technology(5G)on channel capacity.The compact 5G high-gain omnidirectional antenna is realized by using a slotted monopole at the top and a symmetrical branch structure in the ground design,which achieves good impedance bandwidth by matching microstrip lines.Simulation and experimental results show that the designed antenna has good omnidirectional radiation characteristics.The frequency band can cover N7(2500~2570 MHz),N38(2570~2620 MHz),N41(2496~2690 MHz),N48(3550~3700 MHz),N77(3300~4200 MHz),N78(3300~3800 MHz),and N79(4400~5000 MHz),the efficiency of low frequency band is 60%,and that of high frequency band is 70%.The test results are basically consistent with the simulation results.
