The design of an ultra wideband antenna (UWB) for communications and ground penetrating radar system presents challenges. There is often a desire for the antenna to be small while maintaining their UWB characteristics. This is especially the case in ground penetrating radar systems that need to fit into buried pipes. In this paper several antenna configurations are examined to meet these requirements. The coaxial gap antenna can be configured into a variety of combinations of radiating architectures, shielding sections and loading elements. The results presented in this paper demonstrate their attraction for Ground penetrating and communications applications.
