Investigation of Convenient Antenna Designs for Ultra-Wide Band GPR Systems

This paper proposes the planar and 3-dimensional ultra-wide band (UWB) antenna types suitable for hand-held and vehicle mounted impulse GPR systems. On this scope, bow-tie, spiral, TEM horn, dielectric-loaded Vivaldi, multi-sensor adaptive and array model antenna configurations are designed, simulated and measured. The numerical and experimental results are presented with performance comparisons.
