一种便携式卫星通信天线的设计

摘要

便携式卫星天线是一种通过卫星中继实现数据传输的卫星通信地球站.文中设计了一种单偏置形式的车载静中通卫星天线,它与正馈形式的卫星天线相比,减少了对馈源波束的遮挡影响,实现了更便捷的收藏方式,并且具有高增益、低副瓣和收藏尺寸小的特点.同时,文中分析了风载荷对天线指向精度的影响,对其进行了设计校核.分析和实测结果表明,设计的天线电气性能优良,结构性能稳定可靠,具有良好的实用性.%The portable satellite antenna works by satellite as small earth base for communication.This paper designs a portable satellite antenna of a single offset reflector.Compared the normal reflector antenna, it could decrease the interference of the radiation, and has the smaller collection size.It has high gain, low sidelobe and miniaturization.This paper designs and analyses the influence of the wind for the precision.The analysis and testing shows the electric property is effective, and the antenna structure is reliable.The antenna is nice and practical.
