摘要共形天线技术是当今天线技术的一个重要分支,从出现就对世界天线格局产生了重大的影响。共形阵列天线对飞行器表面的空气动力学性能的影响很小,不至于改变飞行器的空气动力学性能,这也是发明共形天线的最重要的目的之一,由于共形天线与所附物体的结构保持一致,就不会产生额外的气动阻力,还拥有一系列平面阵列不具备的优点。共形天线技术将在机载、弹载和星载等场合有广阔的应用前景。64802

Title The design and research of Ku-band waveguide microstrip
conformal antenna array
Abstract
The technique of conformal antennas is an important branch of current antenna technique,it brought profound influence on antenna structure of the world since appeared. Conformal array antenna had little impact on aerodynamic performance of aircraft surface,so it does not change the aerodynamics of aircraft performance,which is one of the main purpose of proposed conformal antenna,due to the conformal antenna structure consistent with the attached objects will not cause additional aerodynamic drag, and also has the advantage of a series of planar array does not have.Conformal antenna technology has broad application prospects in airborne missile-borne and space-borne and other occasions.
In this paper, I designed Ku-band conformal microstrip antenna array including:
(1)By understand the background and historical development of conformal antennas, introduced the unique advantages of conformal antennas, and the prospects for development.
(2)Analysis of the works of microstrip antenna unit provided a theoretical basis for design of conformal array.
(3)In order to quickly and accurately design,I used software HFSS to design and simulate, debugging through simulation results data, the final design of microstrip conformal antenna arrays meet the requirements.

1.1 共形阵列天线的发展背景
在二战期间,飞机是作战双方的主要战斗工具之一,作为探测飞机主要手段的雷达就此诞生,并基于此获得了极大的发展。随着航空与航天技术的飞速发展,尤其是20世纪60年代研制的反洲际弹道导弹系统,对雷达提出了远距离、高精度、高分辨力及多目标测量等一系列要求。正是这些诸多的要求促进了雷达技术的蓬勃发展,由单一的靠天线作机械扫描的初期雷达逐步发展到如今的多功能高性能的相控阵雷达系统[1]。 HFSS的Ku波段波导馈电微带共形天线阵列的设计与研究:http://www.youerw.com/tongxin/lunwen_72139.html
