Characteristic Mode-Based Neutralization Line Design for MIMO Antenna

open access: yesInternational Journal of Antennas and Propagation, 2022
Based on the theory of characteristic modes (TCMs), this paper proposes a systematic design procedure to guide the design of a neutralization line (NL) for a dual-band multiple-input-multiple-output (MIMO) antenna to achieve high isolation.
