Dual band compact inset CPW feed antenna with DGS

This paper presents design of antenna for worldwide interoperability for microwave access (2.3–2.4GHz and 2.5–2.69GHz) and Wireless Local area network (2.4–2.484GHz & 5.15 GHz). The proposed design uses inset feed for achieving a good impedance matching with compactness. The fundamental frequency of the design is 2.6 GHz; Implementing defected ground structure provides additional frequency at 5.15 GHz and shifts the fundamental frequency to 2.5GHz. Different lengths of DGS and its effect on antenna performance and resonance frequency are analyzed. High Frequency Structure simulator is used to analyze the design.
