Outline of Final Research Achievements

Flexible microwave and uhf antennas that are made of conductive textiles have been designed and fabricated, and their characteristics have been measured in bending and flat cases. An equivalent circuit model was presented for shorter designing time. Operation problems in bending case and their solution were also presented together with their cause. In addition, a magnetic type small antenna whose characteristics were affected little by items or the human body in the vicinity was proposed. The results obtained in this research would show new potential of wearable antennas and be useful for designing wearable electronic devices.
