We have developed a "Bluetooth Low Energy multi-antenna module" that can detect. Six antennas are mounted on this module, and the arrival angle is calculated from the phase difference of the radio waves received by each antenna. Hosiden's original algorithm is used to calculate the arrival angle, and by removing false detection and noise by multipath, the direction of the communication partner is stably detected regardless of whether it is stationary or moving, and the radio wave arrival angle is calculated. It can be detected within a range of ± 75 ° from the front of the module. A UART interface is provided for module control, and Bluetooth connection and detection processing can be executed / stopped from an external host device.
