| Outline of Final Research Achievements |
Leaky-wave antennas based on composite right/left handed metal waveguides have been realized by installing slots periodically arranged or slits on the metal wall. This kind of antennas has a merit that the radiation beam can seamlessly scan from the backward to the forward directions along the antenna axis when the frequency is varied continuously. The radiation characteristics have been verified from both the numerical calculations and the experimental measurements.

| Academic Significance and Societal Importance of the Research Achievements |
金属導波管だけで反射損失の少ない右手／左手系媒質を構成し、導波管壁にスリットなどを設けることで、それを漏洩波アンテナに応用した例はなく、周波数によるビーム走査が可能なアンテナであることから、今後、物体検知や人感センサなど幅広い応用が期待できる。
