A Dual-band Slotted Antenna with an Asymmetrical T-shaped Stub for Application in WLAN Systems

An dual-band slotted antenna of planar in nature is provided in this paper which is antenna fed by the transmission line of microstrip in nature having a rectangular small patch is erected for proper matching of impedance. The provided slotted antenna is conceptualized by creating an open-ended slot of square in size in the plane of grounded in nature. An asymmetric thin horizontal T-shaped stub is erected from the left bottom side of the slotted area of the plane of the ground. The antenna which is provided resonates at the two frequencies of 2.38 GHz and 5.19 GHz having the bandwidths of percentage (BP) of 22.13 and 60.25 respectively suitable for application in WLAN systems.
