This paper represents a circularly polarized microstrip antenna for much kind of wireless communication applications. Circular polarization can be achieved with asymmetries. The emphasis is on to increase the bandwidth of the antenna. In this paper various kinds of techniques has been used to provide circular polarization like triangular slits inserted at the corners, corners of the patch are truncated etc. The proposed antennas have been discussed with Aperture Coupled feeding. Measured results show that radiation patterns with good CP Characteristics are obtained for multi bands. HFSS software used to simulate the antennas.
