摘要
介质透镜天线是一种新型多波束天线形式,其性能测试方法是迫切需要突破并研究该类天线特性的关键技术。研究给出该透镜天线2类测试方法:单层透镜天线各个端口的方向图性能测试;叠层透镜天线各层各个端口的方向图测试和叠层后整体天线的方向图性能测试。方向图测试的主要性能指标包括天线增益、波束宽度和旁瓣电平等。方向图性能测试主要涉及到的设备仪器包括透镜天线、Ka波段信号源、信标天线以及暗室测试环境。通过试验验证,给出方法满足介质透镜天线的测试要求。
Lens antenna is a new type of muhi-beam antenna,and its performance testing is a key technology for exploring its characteristics.Two methods for lens antenna pattern performance testing are presented：one is the pattern performance testing of each port of a single lens antenna,the other is the lens antenna pattern test of laminated layers of each port and the terrace performance test of the overall antenna pattern.The key performance specifications of pattern tests include antenna gain, beam width and side lobe level, etc.The main instruments involved in the test of antenna pattern performance include lens antenna, Ka-band signal source, beacon anten- na and darkroom test environment.The test verifies that the methods meet the test requirement of dielectric lens antenna.
