Study of multi - band property of rectangular microstrip patch antenna having different numbers of wide slots 具有不同宽槽数的矩形微带贴片天线多带特性研究
As far as the author knowledge , the most board s11 - 10db bandwidth of 130 % is seen in the presented papers 本人所见到的目前报道的宽槽天线最大带宽为130 % 。
As far as the wide slot antenna is concerned , a broad s11 - 10db frequency bandwidth of 158 % and an operating frequency band of 1 . 9 ~ 16 . 25 ghz are produced by applying this method to it 对宽槽天线而言,应用这种方法得到了阻抗带宽为158 %的超宽带宽槽天线,工作频率为1 . 9 ~ 16 . 25ghz 。
The main content of chapter ii describes the positive influence of rounded corners on keen vertexes of wide slot antennas and bowtie ones . a great deal of experiments and simulations prove the conclusion mentioned above 第二章主要讲述在宽槽天线( wideslotantenna )和多个蝴蝶结天线( bowtieantenna )辐射面的尖锐顶点处倒圆角对天线性能的改善作用。
Indent rubber board en - ditch rubber board , dim red , relative dents and ditches are designed for inner layer , better in positioning lest side gliding ; inosculate fully in operation , with higher transition efficient and smaller gliding factor , and that shall be beneficial to silver quality 内齿胶板,内宽槽胶板,暗红内层设计相应的齿、槽,上机定位性好,不易跑边,运转可充分吻合,传动效率高,滑溜系数小,有利于提高成条质量。
This method rounding the keen vertexes on the plane antennas fits for not only wide slot antennas and bowtie antennas but many other plane ones . the method is not applied first in the thesis ; however , the foregoing papers did not do some summarizations on it 这种在天线尖锐顶点处倒圆角来改善天线性能的方法不仅仅适用于宽槽天线和蝴蝶结天线,对很多平面天线也是适用的,此论文并非第一个应用本方法的工作,但是前人并没有对此进行总结,本文总结的这一改善天线性能的方法得到多篇已发表的文献支持。
