Abstract:Ultra wideband (UWB) technologies have been proposed and validated for potential high data rate communication systems. In this paper we present some recent works in our group, namely the Research Institute of Electronic Science and Technology (RIEST), University of Electronic Science and Technology of China (UESTC). The development is mainly focused on the miniature and broad band capability, as well as some special requirements, for instance, band-notched characteristics and diversity performance for multi-input multi-output (MIMO). Four compact printed broad band antennas are discussed in total, including an ACS-fed UWB and Bluetooth antenna, an UWB microstrip antenna with dual band notched characteristics and a high-isolation orthogonal diversity UWB and Bluetooth antenna for MIMO applications. At last, a MIMO UWB antenna with a rejected band is proposed
