Today, the technological evolvements have contributed to the development of Ground Penetration Radar (GPR) systems. GPR systems are used in a lot of fields such as; military field, civilian life and commercial activities. In this paper, an antenna will be designed as the important part of the GPR system and this is Self-Complementary bow tie antenna was used as frequency independent. According to the results of designed antenna to increase the bandwidth, frequency starts from 0.45 GHz and it works frequency independently. Also simulation and fabrication results will be presented.
