This paper presents coplanar waveguide (CPW) fed slot antenna. A rectangular slot antenna is excited by a 50 ohm CPW with L-shaped tuning stub. It can achieves wide band from 2.0 GHz to 6 GHz which is the frequency band covered the standard IEEE 802.11a/b/g for use in WLAN (Wireless Local Area Network) and covered the WiMAX (Worldwide Interoperability for Microwave Access, 2-6 GHz). The characteristics of antenna are proposed and analyzed for instance input impedance, return loss, bandwidth, VSWR, and far field radiation patterns. The antenna is analyzed by using Finite-Difference Time-Domain (FDTD) Method. A verification of our simulation procedure is confirmed by comparing IE3D software which is based on the Method of Moments (MOM).
