摘　　要：本文提出把单线背射螺旋作为短背射天线的馈源时，可得到一种性能优良的新天线。文中给出了螺距角α＝１０°、１２．５°、１６°单线背射螺旋作馈源时的结果。该天线最大增益可达１８．２ｄＢ。此外还具有结构简单、馈电方便、频带宽且易于产生圆极化波等优点。性能远优于带相同接地板的螺旋天线和普通短背射天线。A new backfire antenna of good characters is describo in this paper.It has a new feed-a monofilar backfire helix.Three situations of pitch angles α=10°.12.5°.16°are measured.The antenna has a gain Of 18.2dB.In addition, the new antenna has the advantages of simple structure,easy to fed and Of a 1-1.4 operating frequency range,and a circularly polarized wave is radiated.The characteristics are much better than a helical antenna of the same ground plane and a short back fire antenna.
