摘要： PROBLEM TO BE SOLVED: To provide an encoded information reading (EIR) terminal capable of seamlessly switching wireless communication networks or protocols.SOLUTION: The EIR reading device can be provided by a bar code reading device, an RFID bar code reading device and/or a card reading device. The EIR device outputs raw message data comprising an encoded message and outputs decoded message data corresponding to an encoded message. A wireless communication interface supports at least two wireless communication protocols and/or at least two frequency bands. The multi-band antenna can be configured to simultaneously receive two or more wireless signals in two or more frequency regulatory domains. The EIR terminal dynamically selects a wireless communication network and/or a wireless communication protocol and/or a frequency band by optimizing a value of a wireless communication protocol selection criterion based on two or more wireless signals.

摘要： PROBLEM TO BE SOLVED: To provide an antenna suitable for a radio frequency identification (RFID) tag.SOLUTION: An antenna can be provided by a patch cell 210a (a patch cell array comprising two or more patch cells) or by a patch cell stack comprising two or more patch cells. An equivalent circuit for the patch cell 210a can comprise at least two inductances 242a, 244a and a shunt capacitance 246a. An equivalent circuit for the patch cell array can comprise two or more inductance groups connected via a series capacitance and two or more shunt capacitances. An equivalent circuit for the patch cell stack can comprises two or more capacitances connected via a series inductance and two or more shunt inductances. The antenna can have a composite right- and left-handed (CRLH) structure.
