3D Printed 90 GHz Frequency-Coded Chipless Wireless RFID Tag

This paper presents the design and measurement results of a 4-bit chipless 3D printed ceramic wireless RFID tag in alumina. It is shown how the accuracy and material quality of the recently presented manufacturing method for millimeterwave components can be used to implement photonic crystal high-Q resonators. Wireless measurements of a four-resonator RFID tag show a loaded quality factor of 902 and a radar cross section equal to -43.3 dBsqm at 90.4 GHz.
