CPW-Fed antenna based on Metamaterial for Broadband application

A Broadband antenna realized by CPW-Fed antenna (coplanar waveguide), this is loaded with split ring resonator (SRR) as metamaterial unit cell. The aim of this work is to exhibit the improvement of the gain and the band width by metamaterial inclusion. The obtained results from HFSS simulation concerning the constitutive parameters of the (SRR), show that there is a DNG (Double Negative) permeability and permittivity in the frequency of interest. In this work the operating bandwidth of the proposed antenna (notched band) is in the range of 0.43GHz to 0.95 GHz as DVB-T band, and 1.5 GHz to 2.5 GHz as Wi-Fi application. Here in this paper the inserted SRR has a remarkable effect in the second band.
