In this paper, a dual-frequency printed slot antenna loaded with an open-ring conducting strip and capacitively fed by a coplanar waveguide(CPW) is designed. The designed antenna has a bandwidth of 240㎒(1690㎒-1930㎒) at PCS frequency band and of 160㎒(2380㎒-2540㎒) at WLAN frequency band. In both frequency ranges, pattern and gain requirements are satisfied. The commercial software, IE3D, was used to design slot antenna. The predicted characteristics along with measured data are presented for verification purpose.
