Abstract (in Japanese) (See Japanese page) 
(in English) In the fifth-generation mobile communication system (5G), the utilization of millimeter wave band is highly expected to increase its communication capacity drastically. Because the radio propagation mechanism in the millimeter wave band is quite different from the conventional microwave band, it is the crucial issue to clarify how it differs in various conditions for validating the network deployment strategy. Author's research group has conducted channel measurements in several super high frequency (SHF) bands and investigated the frequency characteristics of the propagation channel to solve the issue.
In this paper, we conducted the single-input multiple-output (SIMO) channel measurements in 3 GHz, 10 GHz and 28 GHz bands in a small room environment.
The measurements were conducted by forming the cylindrical virtual array at the same antenna position and in the same measurement bandwidth. The measurement results showed that the decay factor of the power delay profile was large, and the specular reflection signal component was significant in the higher frequency band. The results are expected to be utilized for the system deployment issue for the millimeter wave communication system.
