A novel technique in chipless RFID systems is presented providing high data capacity on a fully printable tag. Tag structure includes small polarizers that orthogonally backscatter signal respect to the interrogation wave. The reader utilizes a simple continuous wave (CW) form on its separate TX and RX antennas. The fully printable tag is capable of carrying up to 35 bits in a credit card size while...
A fully printable 60 GHz chipless RFID tag provides high data capacity. The printed tag consists of an array of 45° inclined conductive microstrips that act as perfect electromagnetic (EM) polarizers. When illuminated with a linearly polarized signal, the tag's backscattered cross - radar cross section (RCS) response is much larger than its co-RCS. The tag can encode up to 50 bits of binary data in...
