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 module is formed with a transmission line coupled to an RF phase splitter, where in one embodiment, the transmission line is formed from two parallel conductive strips.
