| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a novel dual frequency reflectarray whose elements have not only the desired reflection phases but also the same amplitude among them. In design of a reflectarray, we employ the particle swam optimization (PSO) which simultaneously achieves desired amplitude and phase shift at both frequencies of 1.0 GHz and 1.5 GHz. Two-layer structure is adopted to increase design freedom. In the two layers, the presence or not of a 4 by 4 metallic patch on mesh is determined by PSO, and moved in axial symmetry about x- and y-axes. As a result, we develop a dual frequency reflectarray with which the plane wave is radiated in direction of -30 degrees when the angle of incidence from illuminator is 0 degree. | |
