Abstract:

The design of three antennas of triangular microstrip patch with a stub at the tip for circular polarization is 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 the proposed three antennas is 1.43% for 1st, 1.48% for 2nd, and 2.22% for 3rd antenna structure. The return loss bandwidths of the three proposed antenna structures are achieved as 5.6% for the first, 5% for the second, and 5% for the third antenna structure. The realized gain, efficiency, and radiation patterns were also studied. A detailed study of all three antenna structures is given in this paper.

Keywords:
