It has the characteristics of the small volume, light weight, high apertureefficiency and low wide-angle minor lobe and so on.
它具有体积小、重量轻、口径效率高、宽角副瓣低等特点。

Numerical results show that the effect of metallization thickness is smaller on the direction of main beam and very noticeable on the beamwidth and apertureefficiency.
数值结果表明，金属栅厚度对漏波天线波求方向影响较小，但对漏波天线的辐射效率和波束宽度有明显的影响。
