Abstract
With the advantages of low power consumption,high transmission speed and good confidentiality,the UWB tech-nology has broad prospect in application and development of space navigation,space communication and radar. The latest re-search progress of UWB technology around the globe is summarized in this paper. The functions,characteristics and some key points of UWB microwave filter are introduced. The design methods ( z transform technique,multimode resonator technique and filter cascaded technique) and structures (microstrip structure,multilayer structure,cavity structure and new materials) of UWB filters are discussed and illustrated. The development trend of miniaturization,high integration and high performance UWB fil-ters is prospected.关键词
