| Outline of Final Research Achievements |
With the spread of ultra-high-speed wireless systems, tightness of frequency resources is becoming a serious problem. It is effective to introduce high-speed wireless transmission methods such as Multiple-Input-Multiple-Output (MIMO) technology in unused frequency bands as a measure against the tightness of frequency resources. In this research subject, high-performance antenna technologies applicable to high-speed wireless transmission system in unused frequency band have been developed. Antenna technologies for constructing MIMO antenna systems in unused frequency bands have been developed. Based on these technologies, multiport MIMO antennas have been developed.
