Optimized performance result for 2.4 GHz and 2.45 GHz circularly polarized microstrip antenna

A deployment of the RF devices especially for antenna should be done continuously to obtain the better performance than the existing. The better performance means that the antenna has the matching impedance closed to perfect condition, higher gain and also better alignment which is related to antenna polarization. To get the better performance, the antenna should employ circular polarization which has advantage in alignment. The optimization of the antenna should be done to improve the performance. In this paper, the optimized antenna can covers between 2.4 GHz–2.45 GHz of Frequency with the increased gain and circular polarization which generally have better performance compared than existed antenna.
