Title:
WIRELESS COMMUNICATION DEVICE, AUTOMATIC DOOR, AND AUTOMATIC DOOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/142678
Kind Code:
A1
Abstract:
This wireless communication device (90) comprises an antenna (60) and is used for an automatic door. The antenna (60) is provided with a first conductor (31), a second conductor (32), one or more third conductors (40), a fourth conductor (50) and a power supply line (61). The first conductor (31) and the second conductor (32) face each other in a first direction. The one or more third conductors (40) are positioned between the first conductor (31) and the second conductor (32), and extend in the first direction. The fourth conductor (50) is connected to the first conductor (31) and the second conductor (32), and extends in the first direction. The power supply line (61) is connected to one of the third conductors (40). The first conductor (31) and the second conductor (32) are capacitively connected to each other via the third conductors (40). The fourth conductor (50) faces a conductor part of an automatic door.
