Abstract: The rationale behind our work is that a small planar antenna is proposed using DNG (Double Negative) metamaterials. The double negative property is being obtained by introducing conductance, inductance and capacitance in the antenna structure by inserting a via (cylindrical hole) and gaps in the antenna patch. 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 3.768 dB, a radiation efficiency of 99.11% and a WSWR of 1.6 at 5 GHz frequency which is very good for point to point wireless communication and wireless LANs. Our antenna has better VSWR, gain and radiation efficiency compared to an ordinary patch antenna.
