Abstract: The rationale behind our work is that a small planar resonating antenna is proposed using DNG (Double Negative) metamaterials. The double negative property is being obtained by inserting series capacitors and shunt inductors using plates and via respectively. Metamarerials are artificial materials having negative permeability, permittivity and refractive index and due to this it exhibits unusual properties compared to readily available materials. Due to the unusual properties of the metamaterials here we got a better gain of 5.197 dB, total efficiency of 92.5% and a return loss of -13.5 dB at 5 GHz frequency and the gain, efficiency and return loss are 4.183 dB, 60.78%, -14.5 respectively for 2.4 GHz, which are very good for wirelessly access network resources at home and elsewhere with up to 5 GHz performance, like IEEE 802.11a, widely available IEEE 802.11b, downwardly compatible IEEE 802.11g, and advanced IEEE 802.11n. Using this metamaterial antenna the demerits of ordinary patch antenna like low gain and efficiency can be overcome.
