This paper presents a software-based design of an ultra-wideband slot antenna that is applicable for wireless applications. Due to introduction of polygonal wide slot in the ground plane, the ultra-wideband has been achieved. The battery slot and rectangular shapes are implemented to improve S 11 , operating bandwidth range and radiation pattern of antenna. The optimal dimensions of the presented antenna are 45mm × 45mm × 1.565mm and is simulated on FR-4 substrate with relative permittivity of 4.3 and loss tangent of 0.025. The proposed antenna shows wide impedance bandwidth of 4.56GHz (104%) ranging0 from 2.08GHz to 6.64GHz that covers WLAN and WIMAX application.
