  • The ground penetrating radar is greatly expected as an effective tool for nondestructively sensing subsurface environment, detecting and identifying underground objects such as water pipes, power and communication lines, archaeological remains, and so on. However, conventional ground penetrating radar systems are still insufficient for practical uses with respect to reliability, resolution, detectable depth, and so forth. In order to overcome these difficulties, it is important to improve characteristics of signals to be measured. Therefore, the design and development of antennas of higher performances would be invaluable. This paper designed a bow-tie antenna loaded by lumped resistors. Results of finite difference time domain calculation show good fidelity of the wave, and exciting radiation features as well as effect of shielding. It can be widely used in ground penetrating radar and other tra-wide-band systems.
