摘要共形天线（Conformal antenna）是近年来天线领域的研究热点。理想的共形天线可与 载体平台完全共形，甚至可以作为载体平台结构的一部分,不仅能够承重，而且不会影响 其作为天线的各方面性能，因此共形天线的应用前景非常广阔。但是，与传统的平面天 线不同，由于共形天线需要共形于复杂曲面，因此需要借助功能强大的计算机进行分析； 在制作上，共形天线往往还需要新材料的支持，所以目前共形天线的研究还处于初级阶 段，真正意义上的共形天线也非常少见。75940

本论文从圆柱面共形的天线入手，对其性能进行分析研究。主要工作分为三个部分。 一是分析微带天线的谐振频率和物理参数的关系，特别分析在微带天线变形的情况下， 谐振频率的解析公式；对天线单元在 X 面和 Y 面弯曲后的性能变化进行仿真分析，为共 形天线的设计打下基础； 二是设计 SIW 裂缝天线单元，了解其在 X 面和 Y 面弯曲后的 性能变化，分析弯曲 SIW 裂缝天线谐振频率和物理参数关系，通过仿真可以得出 SIW 裂 缝天线在共形天线中的优势；三是进一步设计一个18 的 SIW 裂缝天线阵，分析表明： 在 X 面和 Y 面弯曲的条件下，谐振频率稳定，性能优良，特别适合共形天线的需求。

Title Design and Analysis of microwave/millimeter-wave   Conformal Antenna

Abstract

In recent years, the conformal antenna has become one of the hot research topics。 This kind of antenna can be fully conformal to its carrier, or even part of the carrier to bear the load without affecting its performance as an antenna, so conformal antenna has a bright future。 However, different from conventional antennas, the surface of conformal antenna is quite complicated and needs lots of computing works when analyzing the conformal antenna。 Moreover, sometimes the design and fabrication of conformal antenna depend much on the developments of new materials。 Therefore, so far, very few conformal antenna has been applied practically, a lot of further research work are still required。 In this thesis, we analyze cylinder-bending antenna。 The whole work can be pided into three parts。 In the first part, the design process of patch antenna is learned, and equation of the resonance frequency is analyzed。 Then we design a unit of patch antenna in HFSS, bend it along X- and Y- directions respectively to explore the tendency of the performance change。 In the second part, one SIW slot antenna element is designed and simulated with HFSS, the performance change in cases of different bending along X- and Y- directions are analyzed。 In the third part, 1*8 SIW slot antenna array is designed and simulated with HFSS。 The results indicate that SIW slot antenna is a good candidate to be used for conformal antenna design。
