Printing Device for Printing of Radio Frequency Identification (RFID) Labels

A printing device for printing Radio Frequency Identification (RFID) labels, the printing device comprising:

• an input media drawer configured to receive a plurality of RFID labels, each RFID label of the plurality of RFID labels including at least one RFID tag;
• an RFID label processing mechanism operatively coupled to the input media drawer, the RFID label processing mechanism comprising
• a radio system for providing a signal for processing of the at least one RFID tag of the RFID label, the RFID label received from the input media drawer, and
• an antenna module coupled to the radio system for processing the at least one RFID tag by the radio system using the signal, the antenna module comprising a transmission line, wherein the transmission line comprises a combination of a first set of horizontal legs and a second set of vertical legs, the first set of horizontal legs and the second set of vertical legs connected serially such that each horizontal leg adjoins at least one vertical leg and each vertical leg adjoins at least one horizontal leg, the radio system and the antenna module configured to process RFID tags positioned horizontally and vertically on the RFID labels;
• and
• a printing mechanism operatively coupled to the RFID label processing mechanism for printing on the plurality of RFID labels.
