A Self-Decoupling Method for MIMO Antenna Array Using Characteristic Mode of Ground Plane
IEEE Transactions on Antennas and Propagation, 2023A self-decoupling method for the multiinput multioutput (MIMO) antenna array is investigated. This method is based on the specific characteristic mode (CM) of the ground plane, which features two or multiple parallel null-field regions.

Pattern-Reconfigurable Planar Array Antenna Characterized by Digital Coding Method
IEEE Transactions on Antennas and Propagation, 2020We propose a low-profile and high-gain pattern-reconfigurable planar array antenna (PRPAA) based on digital coding characterization. The radiating elements in the PRPAA are designed ingeniously to realize digital “0” and “1” elements.
