Abstract	This talk briefly introduces design challenges of ultra-wideband (UWB) antennas. An outlined of special design considerations are presented from a systems point of view, followed by some state-of-the-art solutions. Then, the miniaturization technology of UWB antennas is addressed. The planar designs are highlighted due to their unique merits and wide adoption in applications. First, the ground plane dependence of the antenna performance in small antenna design is addressed. Using a newly developed technique, the dependence of small antenna performance on system ground plane is alleviated. A design example is used to elaborate the mechanism of the method. Based on this concept, the antenna with further reduced size is designed to fit the size of wireless USB dongle. Furthermore, an innovative compact diversity UWB antenna shows the advantage of ground-independence small antenna in diversity applications. Last, a UWB antenna integrated with bandpass filter is proposed to reduce the overall size of devices by using the concept of co-design. In the end of the talk, the trend of UWB antenna R&D is offered according to application and market demands.
