Zipper device and communication method

Abstract

A zipper device includes: a zipper pull, a dielectric layer, a connecting metal portion, and a signal source. The zipper pull includes a first metal portion and a second metal portion. The dielectric layer can be used to separate the first metal portion and the second metal portion. The connecting metal portion is coupled to the second metal portion. The signal source has a positive terminal and a negative terminal. The first metal portion, the second metal portion, the dielectric layer, and the connecting metal portion form an antenna structure, wherein the antenna structure can be used to receive or transmit a wireless signal.
