The driven signal of Ground Penetrating Radar (GPR) system usually is wide-band and short pulse, so the antenna must be wide-band. In order to reduce the strength reflective wave at antenna end and improve the detecting effect of the GPR, a novel configuration of bow-tie antenna is presented in the paper. The driving circuit is built in the resistively loaded antenna. In the paper, the radiation characteristics of the bow-tie antenna are studied through Finite Difference Time Domain (FDTD) Method. Numerical simulation results show that the antenna proposed in this paper terminates the reflecti...
