[Poster Presentation] Control of the reception level using the millimeter-wave band waveguide slot array installed on the side in the touchless ticket gate

Abstract (in Japanese) (See Japanese page) 
(in English) One of the touchless ticket gates is a system in which an antenna on the ceiling of the ticket gate radiates a millimeter wave to the floor and communicates with a passenger's smartphone to open the gate. However, the millimeter wave from the ceiling is sometimes blocked by the passengers' bodies and luggage and do not reach the smartphone. Therefore, antennas will be installed on the sides of the gate so that they will not be blocked. The beam radiated by the side antenna should be higher than the minimum operation level in the ticket gate and lower than the given interference level outside the ticket gate. The optimum values are studied by changing the beam width and power of the antenna.
