A Serial Feeding Network with Defected Ground Structure

Journal of Radars, 2014
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.
