Abstract
A SAW radio-frequency identification (RFID) tag has been investigated theoretically and experimentally in the 6-GHz frequency band. In the calculations, the finite thickness of the electrodes, the difference between the acoustic properties of thin-film and bulk aluminum, and the bulk scattering of the SAW energy by the electrodes are taken into account. The computed test RFID tag (with equidistant arrangement of signal reflectors) has been manufactured with the use of electron-beam lithography. It is shown that the measured and calculated RFID-tag time responses to the interrogating pulse are in good agreement and the code-pulse loss level is 50–55 dB.
