This paper summarizes the design and measurements of a quasi-isotropic printed UWB antenna, with the analysis of its performances through defined figures of merit. State of the art and review of some recent patents give us the opportunity to exploit some empirical considerations about the shape and the methodology of conception. A simple structure is simulated by means of CST Microwave Studio to show the possibility of fulfilling, at a defined level, UWB antenna requirements such as matching, fidelity and quasi-isotropy of the radiation pattern with a simple micro-strip design and a standard technology. The design of this antenna is based on considerations about bulbous and bended traveling wave antennas. Results of its characterization in anechoic chamber are quantified in terms of amplitude and phase variation, in order to illustrate the level of dispersion for the different directions. The article presents some promising patents on quasi-isotropic UWB antenna.
