Online published on 8 November, 2017. Abstract This work is mainly focused on improving the principle characteristics of RMPA. Here design of rectangular SRR based metamaterial structure is proposed, which has been superimposed on RMPA at a height of 3.2mm from its ground plane. The resonating frequency of the proposed antenna is 1.896GHz. Simulation results are suggested that the impedance bandwidth of RMPA with proposed metamaterial structure is improved by 20.9MHz and return loss is reduced by 33.83dB. For proving double negative properties (Negative Permeability and Permittivity) of proposed metamaterial structure within the operating frequency range, Nicolson-Ross-Weir method (NRW) has been employed. All the Simulation results have been obtained by using CST-MWS Software.
