Title:
WIRELESS COMMUNICATION DEVICE AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/142445
Kind Code:
A1
Abstract:
According to the present invention, a wireless communication device 90 is able to be worn on a body 11. This wireless communication device 90 comprises an antenna and a mounting fixture. The antenna comprises a first conductor, a second conductor, at least one third conductor, a fourth conductor, and a power supply line. The first conductor and the second conductor face each other in a first direction. The third conductor is positioned between the first conductor and the second conductor. The third conductor extends in the first direction. The fourth conductor extends in the first direction. The power supply line is electromagnetically connected to one of the at least one third conductor. The first conductor and the second conductor are capacitively connected to each other via the third conductor. The mounting fixture causes the fourth conductor to face the body 11.
