大型平面波导阵列天线的结构设计

Structural design of a large planar waveguide array antenna

相比传统的反射面天线,平面波导阵列天线具有结构紧凑、效率高、剖面低、重量轻等优点,尤其大型平面波导阵列天线可用于舰载、车载等平台,对于减小占用空间、简化安装具有重要作用。针对大型平面波导阵列天线结构设计的要求,从天线的结构组成、结构设计、制造工艺等几个方面,详细论述了该类型天线的结构设计和工艺制造的关键点,并提出了使用非金属材料进行天线设计加工的设想。

Compared with the traditional reflector antenna,the planar waveguide array antenna has many advantages such as compact size,high efficiency,low section,and light weight.Especially,the large planar waveguide array antenna can be applied to ships and vehicles,with important effect to reduce space and simplify installation.According to the requirement s of structural design of large planar waveguide array antenna,this paper discusses the key point for the antenna in view of structural composition,structural design and manufacture technology,and presents the prospect for structureal design of the antenna by use of nonmetal materia.
