卫星多波束天线不规则馈元阵形赋形的研究

本文着重研究了卫星多波束天线馈元阵的形状对赋形的影响.首先证明了常用的通用阵形中存在着对赋形没有贡献的冗余馈元,进而提出采用没有冗余馈元的不规则阵形来赋形以减小馈元数量的思路,并进一步证明了不规则阵和相应的规则阵在同样条件下,用同一种赋形算法,有着同样的赋形效果,最后给出了由通用规则阵得到相应不规则阵的简单而有效的方法.

Research on Pattern Synthesis for Irregular Feed Array Configuration in Satellite Multiple-Beam Antennas

In this paper the effect of feed array configuration in satellite multiple beam antennas on pattern synthesis has been investigated. First it is proved that some redundant feeds which have no contribution to pattern synthesis exist in regular configuration feed array,such as hexagonal grid array. Then a type of irregular configuration feed array with no redundant feed is proposed to reduce the number of array feeds and proved to have the same performance in pattern synthesis as the regular one. In the end a very simple and effective method is presented to derive the configuration of irregular feed array from its regular counterpart.
