摘　　要： 设计了一种工作在毫米波段,与圆锥载体共形的4×4微带天线阵列。采用一种不同于传统的微带馈电方式——底边馈电方式设计矩形微带贴片单元,利用该单元构成平面4×4阵列,通过各向同性变换方法将此平面阵列共形于圆锥栽体表面。采用基于有限积分算法的CST三维电磁仿真软件对该设计进行分析,并研究了圆锥曲率对共形天线辐射性能的影响。结果表明,微带天线单元和锥面共形4×4阵列的中心频率均为35GHz,而圆锥曲率对天线辐射性能最大的影响是增益随着曲率的减小而增大。 The design of a4×4 elements 35GHz conical conformal microstrip patch antenna array on a cone is presented.A new kind of microstrip feed approach,which is a hemline feed method,is used to design the patch element.And this kind of elements are used to form a conformal microstrip antenna array.The influence of the conical curvature on the radiation features of the conformal antenna array is discussed.Simulation results of the CSI'MICROWAVE STUDIO show that this design is applicable,and when the center frequency of the conical conformal antenna array is 35GHz as well as its element,the conical curvature has the greatest effct on the gain of the antenna ar- ray.The gain increases when the conical curvature decreases.
