Title:
ANTENNA, WIRELESS COMMUNICATION DEVICE, BIOMETRIC SIGNAL MEASUREMENT DEVICE, AND GARMENT
Document Type and Number:
WIPO Patent Application WO/2018/180629
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an antenna which is flexible and of which performance is not decreased after bending or repeated washing, a wireless communication device, a biometric signal measurement device, and a garment. The antenna of the present invention comprises, at least, an electrically conductive fiber structure in which an electrically conductive polymer including carbon atoms is carried on a surface and/or in a monofilament gap of fibers with a diameter of not less than 100 nm and not more than 1000 nm. The antenna is characterized in that a mixture of the electrically conductive polymer and an olefin-based resin is used as a primary component, and that a conductive resin observed in a region of 15 to 30 μm from an upper layer is impregnated with an area ratio of not less than 15%.
