一种Ka频段“瓦式”有源相控阵天线设计

Design of a tile-type active phased-array antenna in Ka-band

在Ka频段,由于单元间距小和集成度高,采用"瓦式"结构集成,有源相控阵天线设计难度大。提出一种Ka频段"瓦式"有源相控阵天线设计方法。采用多功能集成芯片技术实现"瓦式"TR组件的设计,"瓦式"有源相控阵天线的整体架构采用模块化设计。最后设计了一种电控扫描的有源相控天线,采用软件仿真和数值分析设计,加工制造原理样机,测试性能指标,验证了提出方法的可行性。

Since the active phased-array antenna is difficult to design the tile-type structure due to the small element spa- cing and high integration in Ka-band, a design method of the tile-type active phased-array antenna in Ka-band is proposed. The multi-functional integrated chip technology is used to design the tile-type T/R module. The overall architecture of the tile-type ac- tive phased-array antenna is designed in modularization. An active phased-array antenna with a function of electronic control scanning was designed. The software simulation and numerical analysis are used to design and manufacture a principle prototype. The performance index of the antenna was tested to verify the feasibility of the method.
