提高正馈式双反射抛物面天线接收和发射效率的卫星天线
摘要：
本发明公开了一种提高正馈式双反射抛物面天线接收和发射效率的卫星天线，包括天线通信组件和支撑组件；所述天线通信组件包括第一反射面、第二反射面、合为一体的馈源射频机构、设备盒；所述馈源射频机构位于第一反射面和第二反射面之间；所述设备盒位于所述第一反射面的底部或支撑组件上，并且与馈源射频机构电连接；所述馈源射频机构内含有对信号进行放大处理的功率放大器和低噪声放大器。采用本发明所述的提高正馈式双反射抛物面天线接收和发射效率的卫星天线，减少了发射损耗，提高接收信号的G/T值。
摘要（英）：

The invention discloses a satellite antenna for improving receiving and transmitting efficiency of a feed forward double reflection parabolic antenna. The satellite antenna comprises antenna communication components and support components. The antenna communication components comprise a first reflecting surface, a second reflecting surface, an integrated feed radio frequency mechanism, and a device box. The feed radio frequency mechanism is between the first reflecting surface and the second reflecting surface. The device box is at the bottom of the first reflecting surface or on the support component, and is electrically connected with the feed radio frequency mechanism. The feed radio frequency mechanism has a power amplifier for amplifying a signal and a low noise amplifier. Through adoption of the satellite antenna for improving receiving and transmitting efficiency of the feed forward double reflection parabolic antenna, transmitting loss is reduced, and the G/T value of signal receiving is improved.
