| Outline of Final Research Achievements |
A wideband scattering performance of a log-periodic dipole array element was clarified numerically and experimentally. A reflectarray which was composed of the log-periodic dipole elements was designed and fabricated. Scattering performance of the fabricated reflectarray was demonstrated via measurements in our radio anechoic chamber.
On the other hand, an efficient design method of a reflectarray was proposed. CPU time of the proposed design method was kept much smaller than that of the conventional methods. Moreover, an optimization method of the reflectarray was also proposed. Numerical simulation was performed and gain enhancement of the reflectarray was observed.
