摘　　要：测试天线波瓣图是分析天线性能的重要方法,随着毫米波天线的大量应用,如何开发出部署灵活,成本较低的毫米波天线测试系统,成为毫米波天线大批量生产的关键,针对此问题,开发出了基于机械臂的毫米波天线测试系统;同时,针对目前平面天线测试系统测试功能单一的问题,基于机械臂的毫米波天线测试系统,不仅能够执行平面近场测试,还能够进行柱面近场、球面近场以及远场测试任务;通过对机械臂实际的精度测量实验和机械臂关键运动参数的计算,验证了基于机械臂测量毫米波天线的可行性并为系统软件设计提供了理论基础;通过与传统平面天线测试系统测试数据比较,增益偏差0.73%,波束宽度偏差1.4%,副瓣偏差1.37%,测试结果一致性较好;实际应用表明该系统能够满足毫米波天线的测试需求,为毫米波天线测试提供了重要手段。Testing antenna lobe pattern is an important method to analyze antenna performance.With the extensive application of millimeter wave antennas,how to develop a millimeter wave antenna test system with flexible deployment and low cost,it has become a key in the mass production of millimeter wave antennas.To solve this problem,a millimeter wave antenna testing system based on a manipulator is developed.At the same time,in view of the single test function of current planar antenna testing systems,the millimeter antenna testing system based on the manipulator can not only perform the planar near-field test,but also implement the cylindrical near-field test,spherical near-field test,and far-field test.The feasibility of millimeter wave antenna measurement based on the manipulator is verified by the actual precision measurement experiment and the key motion parameter calculation of the manipulator,which provides the theoretical basis for the system software design.Compared with the data of traditional planar antenna testing systems,the gain deviation is 0.73%,the beamwidth deviation is 1.4%,and the sidelobe deviation is 1.37%.Practical applications show that the system can meet the test requirements of millimeter wave antennas,and it provides an important means for millimeter-wave antenna testing.
