Abstract :
In this paper, broad beam circular-polarized microstrip antennas are studied. Using a corner-truncated structure with conducting post[1], a patch antenna with a height of 0.1λ only is designed and exhibits a 3dB gain beam width of over 160°, but the axial ratio is poor. Then a stacked squared-ring microstrip antenna is designed using hybrid perturbation method in order to increase 3dB AR beam width. Simulation results for operating at 2.06 GHz are presented and discussed.
