摘　　要：为满足超宽带天线方向图和增益测试的需要,设计了一套超宽带天线测试系统.该系统采用一维转台配合升降塔硬件,在发射端与接收端均采用架高设计,减少了外部环境对测试结果的影响.通过宽频带扫频测试方法获取天线频域测试数据,应用时域滤波方法提高测试精度,测试软件采用模块化、层次化的集成方式,具备多种参数分析、比较功能,提高了软件的可维护性,缩短了开发周期.测试结果表明,该系统能实现在0.1~18GHz频带下,对天线的方向图性能与增益指标进行高精度测试,并可进行数据的处理、分析与显示.In order to meet the needs of an ultra-wideband(UWB)antenna pattern and gain test,this paper designs a test system of UWB antenna.The system adopts one-dimensional turntable and lifting tower hardware,and uses elevated-frame design at both transmitting and receiving ends,which reduces the influence of external environment on test results.Using the wideband sweep test method to obtain test data of the antenna frequency domain,the time-domain filtering method to improve the test accuracy,and the modular and hierarchical integrated mode to test software have a variety of parameter analysis,comparison function,improve the software maintainability,and shorten the development cycle.Test results show that the system can realize the high precision measurement of antenna pattern performance and gain index in the frequency band of 0.1-18 GHz,and can also process,analyze and display the data.
