摘要
阿基米德平面螺旋天线是一种可用在 L 波段、C波段或更高波段的宽频带天线 ,在驻波比小于 2 .5 :1时 ,带宽可达到 4 0 :1,但其效率却不到 4 0 %。当效率提高时 ,带宽又只有 2 :1左右。文中介绍一种自补型阿基米德平面螺旋天线 ,它的效率较普通阿基米德平面螺旋天线高出约一倍 。
The Archimedean plane spiral antenna is a broad-band antenna. It can be used for L and C or more higher wave band.This antenna will be benefited by a bandwidth as great as 40:1 when the VSWR is smaller than 2.5,but its radiation efficiency is only about 40 percent. When the efficiency is improved,its bandwidth will be only about 2:1.This paper mainly describes the self-compensated Archimedean plane spiral antenna.Its radiation efficiency is nearly twice of ordinary Archimedean plane spiral antenna.and its bandwidth is more than 10:1.
