| Outline of Final Research Achievements |
As novel RF reflection/transmission elements, high performance reflectarrays which have characteristics of both reflector antennas and array antennas have been developed. As a result, effective design procedure to improve radiation characteristics is proposed. Furthermore, to suppress scattering waves for carpet cloaking and illusion cloaking, the developed design procedure is applied to elements to construct these cloaking devices. Then, use of electromagnetic optimization for broadband application provides good radiation characteristics. On the other hand, transmitarrays with low insertion loss and wide bandwidth is designed by using multiple resonant elements. And also, as an application to a small radiation system, horn antennas with high efficiency and beam tilt are developed by use of multiple modes.
