| 摘 要： | 本文设计了一种自适应的毫米波多波束天线.采用一种新颖的馈电方式来产生低副瓣、高增益、高邻近波束重叠的窄波束.并且采用数字波束形成技术来产生多波束.仿真和计算结果表明,这个天线的波束波瓣宽度可以达到1°,并且副瓣电平低于-25dB.采用自适应技术后,可以得到小于-30dB的理想零陷.

| Abstract: | A 44GHz self-adaptive multiple-beam antenna was designed.Low sidelobe,high gain and high adjacent beam overlap are generated by adopting a novel way of feed.Multiple beams are generated by employing digital beam forming techniques.Simulation and computation have shown that narrow beams diameter of one degree,low sidelobe and crosspolar levels of -25dB are achieved.The adaptive antenna realizes null depths of better than 30dB. |
