Characteristics Analysis of Reflection and Transmission According to Building Materials in the Millimeter Wave Band

Millimeter wave is the propagation of short wavelength and wide bandwidth. Since the advantages of the millimeter wave band include miniaturization, weight reduction of components and a lot of information transfer, it has become an alternative frequency band for next-generation mobile communications. Also, it is strongly affected by climate and geographic features. So, characteristics analysis of reflection and transmission is required to use the millimeter wave band effectively. In this paper, we measure and analyze reflection and transmission characteristics according to various building materials from 13GHz to 28GHz in the millimeter wave band. For reflection measurement, we measured received power reflected from materials with changing incidence and reflection angles. For transmission measurement, we measured received power penetrating materials with changing reception angle. From these measurement results, we analyzed reflection and transmission characteristics according to building material and change of angle from 13GHz to 28GHz in the millimeter wave band.
