WIRELESS COMMUNICATION DEVICE, AUTOMATIC DOOR, AND AUTOMATIC DOOR SYSTEM
A wireless communication device (90) includes an antenna (60) and is used for an automatic door. The antenna (60) includes a first conductor (31) and a second conductor (32), one or more third conductors (40), a fourth conductor (50), and a feeding line (61). The first conductor (31) and the second conductor (32) face each other in a first axis. The one or more third conductors (40) are located between the first conductor (31) and the second conductor (32) and extend in the first axis. The fourth conductor (50) is connected to the first conductor (31) and the second conductor (32) and extends in the first axis. The feeding line (61) is connected to any one of the third conductors (40). The first conductor (31) and the second conductor (32) are capacitively coupled to each other via the third conductor (40). The fourth conductor (50) faces a conductor part of the automatic door.
