ELECTRONIC SHELF LABEL SYSTEM

摘要

An electronic shelf label (ESL) system is disclosed. The ESL system includes a shelf, at least an ESL, and a radio-frequency (RF) signal transceiver. The ESL is disposed on the shelf. The ESL includes a RF antenna, and the RF antenna defines a signal transmitting H-plane. The RF signal transceiver transceives data with the ESL through the RF antenna, wherein, a connection line between the RF signal transceiver and the RF antenna has an included angle smaller than a pre-determined angle with the signal transmitting H-plane of the RF antenna.
