  • MULTI-INPUT MULTI-OUTPUT ANTENNA FOR IMPROVING ISOLATION
    Publication number: 20110148736
    Abstract: A multi-input multi-output (MIMO) antenna for improving isolation is provided. Split ring resonators (SRRs) are structurally arranged on the lower end of a ground surface between a plurality of antenna patterns spaced apart from each other. Accordingly, permeability of the SRRs has a negative value, which prevents current from flowing between antennas. Consequently, the isolation characteristic of the antennas is improved.
