Efficient technique for Improvement of Axial ratio Bandwidth of Circularly polarized micro strip Antenna

Pragati srivastava, Santosh kumar

Microstrip antennas can provide circular polarization. Wireless field facing a problem of multipath fading. This improves by improving axial ratio bandwidth .In this paper axial ratio bandwidth enhanced by improving shape, structure of microstrip antenna. Circular polarized antenna designed with the help of HFSS software simultaneously study the parameter of circularized polarized antenna having FR4 material. Axial ratio bandwidth increases from 43%to 50%. Microstrip antenna, Axial ratio,HFSS,FR4.
