基于微带贴片天线在无线引信中的应用,设计了一种中心频率为7.2 GHz的同轴馈电圆形微带天线,该天线介质基片相对介电常数为εr=4.4,回波损耗小于-20 d B,天线增益大于5 d B。根据微带天线原理,通过HFSS软件设计的天线,实验结果表明:天...基于微带贴片天线在无线引信中的应用,设计了一种中心频率为7.2 GHz的同轴馈电圆形微带天线,该天线介质基片相对介电常数为εr=4.4,回波损耗小于-20 d B,天线增益大于5 d B。根据微带天线原理,通过HFSS软件设计的天线,实验结果表明:天线谐振频率、回波损耗等性能参数符合设计要求。展开更多
文摘In this paper, data restoration of still image using only the edges data of data loss region by Coons fractal patches is introduced. The simulation tests show that the approach is fast, effective and having extensive applications. Meanwhile, we discuss the different kinds of Coons fractal patches based o the difference of information loss regions.
