Abstract :
In this paper a broadband circularly polarized square slot antenna is presented. The geometry of the antenna is influenced by the structure. Compared to the structure, the present design could significantly reduce the cross polarization, which makes the antenna attractive. The novelty in the structure is that, it has separated the horizontal and vertical components of the L-probe and placed them on the front and backside of the antenna. Also the disadvantage of cross polarization in structure [4] could be considerably reduced to a large extent by the present antenna design.
