摘要
设计了一种结构紧凑通用性强的宽频带、高增益、双极化天线单元与阵列。采用开放式可扩展模块化的设计方法^([1]),提出以16单元为子阵可扩展的64单元双极化阵列天线。仿真及实测结果表明,天线相对带宽为39%(VSWR<1.5),频段范围为3.5 GHz～5.2 GHz,单元方向图旋转对称,中心频率增益为8.8 dB,64单元天线阵列的中心频率增益可高达26.8 dB。该仿真和设计结果可为射电天文阵列馈源以及第5代移动通信系统基站天线设计提供参考。
A compact dual-polarized antenna element and array are designed with wide bandwidth,high gain and general-purpose properties.Method of open scalable modular[1]is introduced to design the 64-element array antennas based on sub-array of 16 antenna unit.The simulation and experimental results show that a relative bandwidth of 39%(VSWR<1.5)and the gain of 8.8 dB at center frequency can be realized.The antenna works from 3.5 GHz to 5.2 GHz and the radiation pattern has a good rotational symmetry.When the antenna element is applied in the 64 unit array,the gain at the center frequency is up to 26.8 dB.The results can provide reference for the design of multi-beam and phased array feed for radio astronomy and formulate index standard of base station antenna in the fifth generation mobile communication.
