N2 - In microwave frequency bands, we have found that the application of spatial division multiplexing (SDM) using a number of antenna arrays is particularly effective for short transmission distances. We were also able to raise channel capacity in short-distance communication to several hundred Gbit/s by utilizing parallel transmission over a 60-GHz band with its wide bandwidth. When utilizing this technology, displacement of TX and RX antennas occurs because of the need to adjust the position of antennas manually by users. Antenna displacement causes deterioration in channel capacity. Electromagnetic field analysis results clarified the impact on channel capacity of antenna displacement that occurs in short-range transmission applications. Our results showed that channel capacity degradation is 10% when the horizontal antenna displacement is 1.5 mm and channel capacity degradation is only 2.7% when the rotational antenna displacement is 10°. The channel capacity degradation is smaller with longer transmission distances.
