当前广泛使用的卫星接收天线为反射面天线。反射面天线是由反射面和馈源两部分组成的,馈源本身叫做喇叭天线。在工程上通常根据馈源与反射面的相对位置,将反射面天线分为前馈天线、后馈天线和偏馈天线三种形式。而从工作原理上来说,常见的卫星接收天线分为旋转抛物面天线、卡塞格伦天线、格里高利天线、球形反射面天线等几种类型。天线的调试工作在安装时已经完 Currently widely used satellite receiving antenna for the reflector antenna. Reflector antenna is composed of two parts of the reflector and the feed, the feed itself is called the horn antenna. In engineering, it is usually divided into feed-forward antenna, feed-back antenna and partial-feed antenna according to the relative position of feed and reflecting surface. From the working principle, the common satellite receiving antenna is divided into rotating parabolic antenna, Cassegrain antenna, Gregorian antenna, spherical reflector antenna and several other types. Antenna debugging work has been completed at the installation
