In the machine to machine (M2M) propagation environment, beam direction changing technique for small antenna like dipole antenna size is required. We proposed to adopt meta-surface to achieve this instead of reflectarray. However, study of beam switching for meta-surface is not enough despite of important for mobile M2M. To address the issue, this paper proposes novel reflected beam switching method...
In the machine to machine (M2M) communication, the propagation environment is worse than that of usual mobile communications, because the terminal equipment is installed in niche space, such as a gap between pieces of furniture. One solution to cope with the bad condition is to apply a high spec antenna, however, it is difficult to change antenna specification because in most cases it should comply...
