In this paper, we present a two dimensional electromagnetic (2D-EBG) square shaped mushroom structure placed between two monopole antennas. Two artificial properties of this 2D-EBG structure such as PMC and Band Reject Region are investigated here. The radiation characteristics of a monopole antenna over this 2D-EBG structure is tested by considering two cases. In the first case monopole antenna is made to operate within band rejection region where as in the second case monopole antenna is made to operate outside the band rejection range. First case is showing an enhancement in operating band width and smoother radiation pattern. In the second case, the effect is null and 2D-EBG acts like conventional plane reflector. The simulated results for both the cases are presented.
