Inhalt:
In this paper meander line antennas with end tip loading, designed for UHF RFID tags are presented. These novel antennas are screen printed on Kapton HN for European frequency band (866-868 MHz) and for North American frequency band (902-928 MHz). Asahi ink is used for screen printing of 25 µm thick antenna traces which remains conductive even after several times sharp bending of these tag antennas. The results show that the antennas exhibit high performance regarding smaller area, high realized gain and better return loss in the frequency band of interest. These antennas are extremely flexible which give autonomy for their applications.
