摘要
目前有源相控阵天线以单频段为主,功能单一,协同工作需要天线数量较多,本文针对该问题设计了一种双频段共口径有源相控阵天线,采用规则嵌阵和错层排布技术将C和Ku双频段集成于一体形成共口径天线单元,设计了高集成数字阵列模块作为信号处理的载体,实现微波与数字信号转换、控制及校准功能一体化,以独立可更换综合网络模块组成阵面架构实现天线单元与数字阵列模块的互联,并通过仿真方式验证电气与力学性能,为双频段有源相控阵天线的结构设计提供借鉴作用。
At present,active phased array antennas are mainly in single frequency band with single function and require a large number of antennas for collaborative work.To solve this problem,a dual-band common aperture active phased array antenna is designed in this paper.The dual-band C and Ku are integrated into a common aperture antenna unit by using regular array and split-layer layout technology.The integration of microwave and digital signal conversion,control and calibration functions is realized,and the interconnection of antenna unit and digital array module is realized by the array architecture composed of independent replaceable integrated network modules.The electrical and mechanical properties are verified by simulation,which provides a reference for the structural design of dual-band active phased array antennas.
