COMPACT SERRATED NOTCH BAND MIMO ANTENNA FOR UWB APPLICATIONS
A compact UWB antenna is been designed to notch Wi Max (3.3GHz 3.7GHz) and W LAN (5.15GHz 5.85GHZ) operating bands. The antenna comprises of two square slottedmonopoles with serrated edges on the patch surface and Tshaped stub as defected ground structure. Coplanar waveguide feeding is used in the antenna structure at two ports with the impedance of 50 ohms. Both simulation and measurement aredone to study the antenna parameters like return loss, radiation characteristics, impedance matching and isolation between the two ports. To enhance isolation a slot is cut on the T shaped ground surface. Two inverted L strips are added on either sides of the groundplane and a slot cut on the ground plane finally form T shape defected ground structure. The proposed antenna notches two application bands in the UWB range with low mutual coupling which makes the antenna a suitable model for desired applications.
