Outline of Final Research Achievements

Fundamental technologies for flexible phased array antenna required for mobile reception system for satellite broadcasting have been investigated, using electro-magnetic simulation and　fabrication process by screen printing method. A new type of flexible, printable and variable phase shifter having low insertion loss characteristics has been developed for the first time. Characteristics of the flexible patch antenna followed by the phase shifter as an antenna unit were also clarified from the power supply point of view. Performance of 4-arrayed system of antenna unit was investigated by simulation as a first step for phased array antenna. It was confirmed that the phase scanning and synthesis of power could be conducted by the above variable phase shifter. These results support the realization of flexible phased array antenna.
