Abstract(in English) | Research and development of communication services using radios and antennas mounted on vehicles, unmanned aerial vehicles , high-altitudeplatform stations, and other mobile vehicles is increasing. Because these communication environments are based on line-of-sight (LoS), the application of LoS-multipleinput multiple output (LoS-MIMO) transmission effectively improves channel capacity. However, angular changes between the transmitter and receiver owing to movement cause degradation of the LoS-MIMO channel and polarization loss. Therefore, designing a system that ensures stable and high channel capacity is necessary. Here, we demonstrate that the proposed array configuration with dual-polarized (DP) antennas is robust against angular changes, and that the array antenna can be downsized and multiplexed by orthogonal polarization through theoretical analysis and experimental verification. |
