Design of impulse UWB volumetric antenna integrating dielectric material

In this paper, a guidelines for designing a volumetric ultra-wideband (UWB) antenna is proposed. The methodology is applied for the design of various travelling waves antenna shapes. A comparative study between various design geometries leads to a particularly interesting antenna dimensions: The K antenna. We demonstrate the use of an appropriate dielectric material is an efficient way to reduce the antenna dimensions. Furthermore, the behavior of an antenna filled with resin intended for Ground Penetrating Radar is validated using the experimental results.
