Abstract: In this study, the design of a novel small size, low profile and multiband octagonal antenna is presented. The design analysis and characterization of the antenna is performed using the Method of Moments (MoM) technique. The new designed antenna has an operating frequency of 1.99 , 2.985 and 3.677 GHz with acceptable bandwidth which has a useful application for new wireless applications. The radiation characteristics, VSWR, reflection coefficient and input impedance of the proposed antenna are described and simulated using 4NEC2 package and NEC viewer.
