摘要

本文提出了一种天线近场计算的新方法．文中详细叙述了用于近场快速计算的卷积积分法．并用该方法得到了偏馈反射面天线的近场分布．文中还将该方法的计算结果与物理光学法的计算结果进行了对比，从而验证了该方法的准确性和有效性．

Abstract

In this paper

a new kind of antenna near field computation method is presented

inwhich the quick convolution algorithm is involved

Some computation results of near field Phaseand’ amplitude distribution corresponding to observation distance and aperture size are shown. Acomparison of this method and PO method is given.
