Abstract :In this paper, we propose an ultrawide band design for the double ridged horn insert ignore into journalissuearticles values(DRH); antenna to be used behind the obstacle radar insert ignore into journalissuearticles values(BOR); applications such as ground penetrating radar insert ignore into journalissuearticles values(GPR); and through the wall radar insert ignore into journalissuearticles values(TWR); imaging. The design is developed and optimized by the help of full electromagnetic simulator code; CST. The design parameters such as frequencies of operation and the half power beam width insert ignore into journalissuearticles values(HPBW); are taken into account by considering the BOR application requirements. The design double ridged horn antenna provides a frequency bandwidth between 1.5 GHz and 7 GHz and HPBW around 30° around the center frequency that are very suitable for GPR and TWR applications. The final optimized design that is formed by CST is physically manufactured and measured. The prototyped DRH antenna’s measurement antenna parameter results are in good agreement with the simulated ones.
