Metamaterial Based Split Triangular Shape Microstrip Antenna

Present paper is based on improvement in gain and the profile of triangular microstrip antenna using metamatrial structure. Widely used metamaterial, engineered for specific purposes, have negative permittivity (ENG) or negative permeability (MNG), or both negative (DNG) with negative refraction coefficient. Author is discussed the antenna with left handed metamaterial (DNG) based structure to enhance the antenna efficiency, reduced the return loss to increase the bandwidth at the same resonant frequency. Simulation is done by using commercial software HFSS, based on finite element method (FEM) and compared with results, obtained from coding. Both obtained results are in close agreement within ~5%. Author is also shown the improvement in gain and bandwidth of simple triangular antenna after using the metamaterial based split ring triangular shape antenna with the help of plots.
