摘　　要：介绍了一种毫米波多层板微带天线。天线工作在Ka频段,四层结构,通过口径耦合馈电,剖面低,重量轻。天线方位面单元采用切比雪夫分布加权,控制天线副瓣的同时差波束对和波束良好覆盖,实现了方向图的和差旁瓣抑制。实测与仿真数据吻合较好。A millimeter multilayer microstrip array with four layers is introduced in this paper. The frequency is Ka band. The antenna is aperture-coupled and has the advantages like thin profile and lightweight. The azimuth elements are weighted by Chebyshev-distribution to achieve low sidelobes and good coverage. The sum-difference side lobe suppression radiation pattern is presented. The measured data agree well with the simulated ones.
