摘要: 本文通過對(duì)FZP反射面偏軸掃描特性進(jìn)行的分析,基于菲涅爾區(qū)相位修正原理,提出一種新型的偏饋FZP反射面天線設(shè)計(jì)方法,并利用物理光學(xué)方法得到一組模擬計(jì)算的數(shù)值結(jié)果。通過與正饋FZP反射面天線的比較,證實(shí)了這種反射面天線具有一些很好的聚焦特性。有關(guān)數(shù)值結(jié)果有助于該類天線的實(shí)際設(shè)計(jì)。

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. -
