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.
