Slit loaded circularly polarized patch antenna embedded on planar structure and curvature structure were investigated. The curvature effect on slit loaded patch antenna determines the limiting value of radius of curvature to obtain circular polarization. At a certain radius of curvature (ROC) around 131.3 mm, circular polarization have been obtained with axial ratio band width around 15 MHz and return loss bandwidth around 56 MHz compared with 17 MHz and 65 MHz as that of planar structure. The beam width responsible for coverage of planar patch are 104 and 107 degree with respect to 84 degree and 124 degree of curved patch at phi = 0 and 90 degree respectively.
