A novel serial feeding network with Defected Ground Structure (DGS) is proposed in this paper. The stripline feed network uses multilayer board laminated structure and DGS on the surface. The output amplitude can be decided by the dimension of the DGS. According to this characteristic, the dimension of the DGS can be modified to realize output amplitude with high precision.%该文设计了一种带缺陷地的串行馈电网络。该串行馈电网络采用带状线多层板层压结构，在串行馈电网络上增加了缺陷地设计。改变缺陷地的大小可以改变相应端口的输出幅度，因此通过调节各端口对应耦合区缺陷地的大小，就可以调节各端口的输出幅度，使得各端口输出幅度接近一致，从而达到提高串行馈电网络电性能的目的。
