摘　　要：双波段天线四功能馈源，属于改进的一种微波天线设备，可以同时传输Ｃ波段收、发信号和Ｋｕ波段收、发信号。通常的一副微波天线只接收一个波段的接收信号、并／或发射一个波段的发射信号．同时接收二个波段、发射二个波段的信号需要用二副天线，本设计可以用一副天线完成。本设计是将Ｃ波段馈源与Ｋｕ波段馈源通过串馈连接做在一个整体上，将它放在抛物面天线的焦点上，通过４个波导输出口与外部信号连接，实现双收、双发的功能。本设计不仅提高了经济效益而且节省了安装天线的占地面积，这对于天线安装在塔尖或房顶上是很重要的。Double band antenna with tetra function feeders is a improved kind of microwave antenna equipment, which could send and receive signals at C-band or Ku-band simultaneously. Usually, one microwave antenna could only send or receire signals at single band. If we want to receive or send at double band, We need two antennas. But this kind of antenna could accomplished the task, without another antenna. The double band sending & receiving function is accomplished by serial connecting the C-band feeder and the Ku-band feeder, and set up the focus of the parabolic antenna, and it's four output point of the waveguide joining to the external signals. The design is more economical and needs less space to install, which is very important for installation at tower and roof.
