摘要
介绍了应用在航空、航天、卫星和导弹上的面天线结构设计,根据微带天线原理,通过S11参数讨论面天线结构对天线尺寸大小、工作频带和辐射增益的影响,为实际设计天线提供理论数据。特别地讨论了脊形接地板高度(脊高)和基片长度对天线性能的影响,并对影响规律进行仿真对比。最后通过HFSS软件对其远近场仿真,仿真结果验证了基于微带天线设计原理设计的平面天线具有结构设计灵活,宽频带,实用性强等优点。
The structural design is described of the aperture antenna on the aviation,aerospace,satellite or missile based on microstrip antenna principle.The impact of structure is discussed which works on the antenna size,the operating frequency band,and the radiation gain to provide theoretical data for the design of the antennas.Particularly,the impact of height of ridge-shaped ground plate and the length of ground plane on antenna performance,and simulate variation are researched.Finally the near and far fields are simulated by HFSS.The experiments show that when an aperture antenna is devised with the microstrip antenna theory,it has many advantages such as flexible structural,broadband,practicability and so on.
