摘　　要：提出了一种适用于第五代(5G)无线通信的宽带印刷偶极子天线辐射单元以及由该辐射单元组成的八单元阵列天线。该天线单元由折叠成“J”形的微带线与“Y”形缝隙槽组成巴伦馈电,采用地板开槽、曲流等技术,减小天线尺寸的同时降低微带天线Q值,从而增加天线的带宽。偶极子设计成倾斜15°的圆弧形,以获得更加稳定的辐射特性。用Ansoft HFSS15电磁仿真软件对天线进行仿真,结果显示,单元天线的相对阻抗带宽为21.46%(27.33~33.90 GHz),增益为5.03~5.74 dBi。阵列天线的相对阻抗带宽为38.6%(24.5~36.2 GHz),最大增益为13.75 dBi,各性能均满足5G毫米波段天线设计要求,在同一类文献中,该天线结构简单、辐射参数稳定,可用于5G移动通信系统和该频段其他无线通信系统中,具有较高的工程实用价值。This paper proposes a broadband printed dipole antenna radiating element suitable for fifth-generation(5mG)millimeter-wavewireless communication and an eight-element array antenna composed of the radiating element.The antenna unit is composed of a micro-belt line folded into a"J"shape and a"Y"-shaped slot groove to form a balun feed,and adopts technologies such as floor slotting and meandering to reduce the size of the antenna and reduce the Q value of the microstrip antenna.Thereby increasing the bandwidth of the antenna.Thereby increasing the bandwidth of the antenna。The dipole is designed to be inclined by 15°to obtain more stable radiation characteristics.The antenna was simulated with Ansoft HFSS15 electromagnetic simulation software.The result is displayed,The relative impedance bandwidth of the unit antenna is 21.46%(27.33-33.90 GHz)and the gain is 5.03-5.74 dBi.The relative impedance bandwidth of the array antenna is 38.6%(24.5-36.2 GHz)and the maximum gain is 13.75 dBi.Each performance satisfies the 5G millimeter-wave band antenna design requirements.In the same kind of literature,the antenna has simple structure and stable radiation parameters,and can be used in 5G millimeter-wave mobile communication systems and other wireless communication systems in the frequency band,so it has comparatively high engineering practical value.
