MULTI INPUT MULTI OUTPUT ANTENNA FOR IMPROVING THE ISOLATION CHARACTERISTIC

摘要

PURPOSE: A multi input-output antenna for improving the isolation characteristic is provided to prevent the flow of a current between antennas by structurally arranging a split ring resonator at the lower side of a ground surface between a plurality of antenna patterns. CONSTITUTION: A first substrate(110) includes a ground surface and a plurality of separately arranged antenna patterns. A second substrate(120) includes a split ring resonator(121). The split ring resonator is arranged at the lower side of the ground surface between the antenna patterns. A plurality of split ring resonators is periodically arranged on a second substrate. A cut-off frequency band is adjusted according to the length of the split ring resonators.
