Mutual Coupling Reduction Using Dumbbell Defected Ground Structure for Multiband Microstrip Antenna Array


A novel design of multiband microstrip antenna array with dumbbell shape defected ground structure (DGS) is presented. The DGS is inserted into the ground plane between the two elements of the antenna array in order to suppress mutual coupling. Both simulation and measurement results verified that the DGS improved the radiation properties of the antenna… (More)
