Multi-beam forming network system

The utility model relates to a multi-beam forming network device. The utility model comprises a power divider, a phase shifter, an isolator and a power synthesizer. The utility model is characterized in that frequency carrying signals are divided into a plurality of paths after passing through the power divider, each path reaches the corresponding input end of the power synthesizer after passing through the specified phase shifter and isolator orderly, and each path is exported to aerial array units through the power synthesizer and forms a scan of beams. The utility model has the advantages that the cost is low, the principle and the conformation are simple, the output phase shift of each frequency carrying signal is linear strictly, and a corresponding power divider and a corresponding power synthesizer are also capable of being chosen to form a suitable multi-beam forming network according to the number of the aerial array unites and the number of beams, so the design the phase controlled array antenna has flexibility.
