Abstract
A novel style is delineated for a circular polarized planar slot antenna. Circular polarization operations is earned exploitation associate degree uneven feeding co-planner conductor. The axial ratio bandwidth can be significantly enhanced by implanting a pair of circular shaped grounded strips at diagonally opposite corners of the rectangular slot. By adjusting the dimensions of the modified inverted L-shaped signal line with circular shaped strip and radius of the circular shaped grounded strips, the circular polarized bandwidth can be achieved as high as 40%. The measured results of this antenna has return loss bandwidth 56% from frequency 2.12GHz to 3.76GHz at VSWR ≤ 2 throughout this band and axial ratio band width 40% from frequency 2.2GHz-3.29GHz at AR ≤ 3dB.
