A Novel Slot-Array Defected Ground Structure for Decoupling Microstrip Antenna Array
IEEE Transactions on Antennas and Propagation, 2020In this article, a novel slot-array defected ground structure (DGS) for decoupling microstrip antenna array is proposed. The slot-array DGS is etched surrounding each antenna element on the ground plane and parallel to the radiating edges of each antenna
