摘要: 本文通过对FZP反射面偏轴扫描特性进行的分析,基于菲涅尔区相位修正原理,提出一种新型的偏馈FZP反射面天线设计方法,并利用物理光学方法得到一组模拟计算的数值结果。通过与正馈FZP反射面天线的比较,证实了这种反射面天线具有一些很好的聚焦特性。有关数值结果有助于该类天线的实际设计。Abstract: A new offset elliptic Presnel Zone Plate Antenna (FZPA) has been suggested based on the Fresnel principle. Simulation of the focusing property of this FZPA and that of the regular one showns that the one suggested here can give better focusing characteristics in some applications. The numerical results give a help to the design of offset FZPA.
