The paper describes the design of an antenna system for a video impulse radar dedicated to landmine detection. The developed antenna system consists of a dielectric wedge antenna as transmit antenna and loop antennas as receive ones. The receive antennas are situated below the transmit one. The dielectric wedge antenna has been designed on the basis of the transmission line model, which has been later verified by means of FDTD modeling. The loop antenna has been designed on the basis of a semi-analytical model. The transient behavior of the antenna system has been investigated both experimentally and theoretically. It is shown that the developed system illuminates a limited spot on the ground surface with a short electromagnetic pulse. The field scattered by objects is received by the antenna system in a local point and without integration over large antenna aperture. The output of each receive antenna reproduces the waveform of the scattered field in a local point. To avoid any mechanical contact with hazardous objects the antenna system should be elevated at least 10cm above the ground.
