Research and development of communication services using radios and antennas mounted on vehicles, unmanned aerial vehicles , high-altitude
platform stations, and other mobile vehicles is increasing.
Because these communication environments are based on line-of-sight (LoS), the application of LoS-multiple
input 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. |
