【摘要】 本文提出了一款对拓Vivaldi天线,天线在5.6 GHz～10.4 GHz的频段内S11<—10 dB。并且通过在辐射贴片外边缘添加栅栏状结构,改善了其辐射方向性,提高了天线的增益。该天线使用相对介电常数2.2的Rogers5880作为介质基板,厚度为0.8 mm,尺寸为56 mm×40 mm,两面印刷。天线在工作频段内具有良好的定向辐射特性与较高的增益。更多还原

【Abstract】 This article proposes an extension Vivaldi antenna,with S11<-10 dB in the frequency band of 5.6 GHz～10.4 GHz.And by adding a fence like structure on the outer edge of the radiation patch,its radiation directionality is improved and the antenna gain is increased.The antenna uses Rogers 5880 with a relative dielectric constant of 2.2 as the dielectric substrate,with a thickness of 0.8 mm and a size of 56 mm×40 mm,printed on both sides.The antenna has good Characteristics of directional radiation and high gain within the working frequency band.更多还原
