Abstract
This paper refers to a detailed analysis on the design and implementation of artificial magneto dielectric substrate and apply to use with microstrip antenna for wireless application. As the results are show the advantage of metal dielectric above conventional antenna. The key advantage of using the metamaterial with microstirp patch antenna is to size reduction of microstrip patch antennas when compare with original antenna. The metamaterial antenna proposed in this paper achieves 11.5% for downsizing in the area of the patch at the same frequency. The modified quadrilateral loop unit cell is used in design. The modified quadrilateral loop unit cell is used in design which the value of permittivity (ϵeff) of 4.8 and relative permeability (μeff) of 2.2. The result found that at the center frequency is 2.45 GHz, the artificial magneto dielectric metasubstrate antenna radiation has the efficiency of 89% and the gain of 6.9 dBi while the conversional antenna has the efficiency of 83.27% and the gain of 5.23 dBi. The performance of the antenna can be improved by controlling the dielectric constant and the magnetic permeability.
