Bandwidth analysis and comparison of slotted patch antenna for wireless applications

This paper discusses the effect of introducing slots of different shapes and dimensions in a rectangular patch antenna to improve the bandwidth. The return loss as well as VSWR characteristics of different patch designs are discussed and compared. The reference design that is E-shaped slot patch antenna has operating frequency of 2.48 GHz. The design implementation aims to achieve optimized results by using coaxial feeds and slots of varying dimensions. The behavior of the results and characteristics of the design is studied and quantitatively analyzed. The proposed antenna can be used mainly for WIFI (Routers), WLAN and Bluetooth applications.
