摘　　要：针对地空通信中浮空平台常用对地天线难以对区域内的用户形成有效覆盖的问题,设计了一款由数面高增益、低旁瓣、定向的天线单元依据波束覆盖要求形成一定空间结构而组成的新型多波束天线。在对微带天线、螺旋天线和喇叭天线进行性能仿真比较分析的基础上,提出选用高增益喇叭天线作为天线阵列单元的方案。仿真结果表明,该设计具有结构简单、覆盖范围广、无需判定用户信号到达方向等优点。It is usually difficult for floating platforms to provide effective coverage for users in the service area by common air-to-ground antennas in air-ground communication.To solve this problem,a novel multi-beam antenna is designed,which is composed of several high-gain,low-sidelobe and directional antenna units forming a certain spatial structure according to the requirements of beam coverage.Based on a performance simulation and comparative analysis of helical antenna,microstrip antenna and horn antenna,a scheme that selects high-gain horn antenna as antenna array unit is proposed.The design has the advantages of simple structure,wide coverage and better reception.
