Abstract
An RFID label with embedded tag is passed through an RFID antenna in a printer system, where the RFID antenna allows a roll of such labels to pass in close proximity to the antenna and still allow each individual RFID tag to be read and/or programmed. The RFID antenna is formed with two parallel microstrip transmission lines coupled to an RF phase splitter there between.
