This paper addresses a problem of size reduction of UWB antennas. We consider the effect of various ground plane modification on achievable miniaturization rate. In order to ensure that the optimum results are obtained, rigorous EM-driven design optimization is carried out involving all geometry parameters of the respective structures. Our investigations are performed using a representative set of...
Size reduction of ultra-wideband (UWB) antenna structures with taking into account matching, efficiency, and radiation pattern constraints is considered. We discuss design trade-offs between the minimum attainable antenna size and its electrical and field properties. The best possible trade-offs are obtained using rigorous numerical optimization of all geometry parameters of the structure at hand...
