Abstract :
In this study, an octagonal shaped ultra wide band (UWB) antenna which radiates at 2.5-18 GHz is designed. The designed antenna covering the entire band is assigned for the UWB applications, which is about 150%. The RCS (radar cross section) of the designed antenna is reduced by modifying the physical structure. RCS of the antenna is reduced up to 25 dB. The proposed antenna is fabricated and the experimental results of the radiation performance are in a good agreement with the simulation results.
