[Poster Presentation] A Study on Scattering Performance of Reflectarrays Using Dielectric Slab

Abstract (in Japanese) (See Japanese page) 
(in English) Wireless communication systems beyond the 5G systems are expected to be developed in a high frequency band over the millimeter wave band. It is well-known that the electromagnetic wave in the millimeter wave band is difficult to be diffracted behind scatterers and its path loss is high. Development of the millimeter wave wireless communication systems for such non-line of sight (NLOS) environment is one of the big problems to be challenged. In this report, a reflectarray covered by a dielectric slab is proposed. The dielectric slab contributes to protect the reflectarray itself and enhance its scattering field strength. According to the electromagnetic theory, geometry of the dielectric slab for maximizing the scattering field strength of the reflectarray element is clarified. Scattering performance of the reflectarray covered by the dielectric slab is demonstrated numerically and experimentally.
