赋形低幅瓣毫米波梳形天线阵的设计与分析

Design and Analysis of a Millimeter Wave Low-side Comb-line Antenna Array

介绍了微带梳形天线阵设计方法,在8 mm波段上分析和设计仿真了一种行波微带梳形阵。阵列单元电流值采用泰勒分布,幅瓣电平优于-25 dB。天线辐射方向图是个漏斗形方向图,具有定向辐射及低副瓣特性。

The design method of a millimeter wave low-side comb-line antenna array is introduced. And basing on the method, a 8mm microstrip comb-line antenna array is designed. The antenna pattern is funnel form, according with the characteristic of directional radiation and low side-lobe. The current distribution of the array is Taylor current distribution, and the side lobe achieves --25 dB.
