- Abstract
- The reflection characteristics of building materials at the millimeter (MM) wave band are needed for development MM-wave application such as Giga-bytes indoor communication systems. Because reflection characteristics in the MM-wave band is dependent on the condition of measurement environments and has so little measurement data. To enhance these problems, we have studied propagation characteristics in the MM-wave band. In this paper, we set up the measurement system and measured the propagation characteristics of samples with periodic and random rough surfaces. Their results compared with measurement and simulation results at the 60 GHz. We have numerical simulation for dependence of electrical property. Also, the energy estimation of scattered reflection according to the rough surfaces simulated. Finally, we propose the simple approach (2 ray path model) for ray-tracing algorithm. This approach can be directly applied to the estimation of multipath signal strength in ray tracing by weighting factor for propagation prediction.
