抄録

This paper gives an overview of the research and development trends in millimeter-wave short-range application systems, such as communication systems and sensing sys-tems, in Japan and other countries. Frequency management trends are also described. Major research and development efforts in Japan have currently been concentrated on the 59-64GHz band. The first major achievement resulting from those efforts was the allocation of the 60-61 GHz band to the automotive radar systems. Test productions of automotive radars in this band have already started. Further technological developments to reduce the cost and size of radar products are, however,required in order for such radar systems to be widely used.Development of broadband wireless LAN systems has also been intensively made in the 60 GHz band. In addition, technical issues related to standardization of millimeter-wave wireless LAN systems in the 60 GHz band have been examined at the Association of Radio Industries and Businesses. The application areas of millimeter-waves in the future are expected to become more diverse. Research and development trends of future appli-cation systems, such as broadband mobile communication systems and imaging radar systems, are also described. These systems require more advance millimeter-wave tdchnologies,such as smart antennas, low power-consumption devices, and more sensitive detectors. Efforts to develop these technologies must be strengthened.
