一种毫米波微带并馈天线阵的设计

摘要

介绍了矩形微带天线的原理和设计方法,并设计制作了2×1的毫米波微带并馈天线阵,运用Ansoft HFSS软件进行仿真调试。辐射方向图表明该天线阵主要向上半空辐射,增益可以达到9.87 dB,阻抗带宽（VSWR≤2）从31.2 GHZ到32.5 GHZ。%Describes the theory and designed methods of rectangular microstrip antenna.Besides,a 2×1 millimeter wave microstrip parallel fed antenna array is presented in this paper,using Ansoft HFSS software to simiulate.The simulated radiation pattern shows that t
