The design of three antennas of triangular microstrip patch with stub at tip for circular polarization are presented in this article. These antennas are designed for maximum axial ratio bandwidth and the whole axial ratio bandwidth lies within the impedance bandwidth. The axial ratio bandwidth of proposed three antennas are 1.43% for 1st, 1.48% for 2nd and 2.22% for 3rd antenna structure. The return loss bandwidths of three proposed antenna structures are achieved as 5.6% for first, 5% for second and 5% for third antenna structure. The realized gain, efficiency and radiation patterns also studied. The detail study of all three antenna structures are given in this paper.
