Design guidelines for the UWB pyramid antenna

In this paper a novel UWB directive and non dispersive lens antenna is presented. It is based on the broad band leaky wave radiation occurring at a slot printed between different homogeneous dielectrics. This paper presents the guidelines for the UWB design, the hardware demonstrator and pertinent measurements. The main motivation for this work was the development of a field sensor for electromagnetic compatibility to be used in the range 4?40 GHz.
