摘要

由罗特曼透镜馈电的阵列天线的副瓣电平可以降低，如果对相邻的波束端口组合，系统通过这些和端口馈电。这个过程不会降低天线的整体增益。说明了这种工作模式的条件，并给出了结果。

Improving the sidelobes of arrays fed by multiple-beam beam formers

The sidelobe level of an array antenna fed by a Rotman lens can be reduced if pairs of adjacent beam ports are combined, and the system is fed through these summing ports. This procedure does not reduce the overall antenna gain. The conditions for this operational mode are explained, and the results are given.
