摘　　要：球面阵列天线具有半空间乃至全空间波束覆盖能力,因而受到广泛关注。但是,球面阵列天线的结构形式比其他天线阵面更加复杂,天线阵面的切块分割更加困难,给天线阵面的布局、阵面骨架的架构、天线子阵的划分以及天线单元的结构设计等带来了很大挑战。文中从球面阵列天线结构设计需求出发,提出了一种新的天线阵面结构布局方案,并给出了阵面骨架、天线子阵、天线单元等的设计思路。通过对阵面骨架进行有限元力学仿真,初步验证了球面阵列天线结构设计的合理性,为进一步研究球形阵面骨架打下基础。Spherical array antenna has attracted extensive attention because of its beam coverage in half space and even the whole space.However,the structure of spherical array antenna is more complex than other forms of antenna array and the segmentation of antenna array is more difficult,which bring great challenges to the layout of antenna array,the architecture of array framework,the division of antenna sub-array and the structure design of antenna unit.Based on the structure design requirements of spherical array antenna,a new antenna array layout scheme is proposed,and the design ideas such as array framework,antenna subarray,antenna unit are given.Through the finite element mechanical simulation of the array framework,the rationality of the structure design of spherical array antenna is preliminarily verified,which lays a foundation for the further research of the spherical array framework.
