摘要
针对数字阵列雷达设计了一种伞形印刷偶极子天线单元。该天线由微带集成巴伦馈电,具有宽频带、宽波束、易于集成等优点。通过仿真和测试,表明该天线有40%的相对带宽,E面波束宽度为80°,H面波束宽度为135°。
An umbellate printed dipole antenna element for digital array radar is designed in this puper. This antenna is fed by an integrated micro-strip bulan. This antenna has the ＇virtue of wideband, wide beam and can be easily integrated with T/R module.By simulation and tested ,it shows that this umbellate printed dipole antenna can achieve 40% bandwidth, and the beam-widthof E-plane and H-plane is 80°and 135° respectively
