“…This aspect of the RFID tag development requires the topology to be exactly calculated with the actual geometry of the electrodes, reflectors, and SAW scattering fields [3][4][5] taken into account, a condition that is necessary for alignment of the amplitudes of the reflected (code) pulses. The high precision has been obtained through the use of the FEM/BEM [6][7][8][9][10]. For the calculation to be exact, it is also necessary to take into account the difference between the elastic properties of the alumi num thin films and bulk material [11].…”

A SAW radio frequency identification (RFID) tag has been investigated theoretically and exper imentally in the 6 GHz frequency band. In the calculations, the finite thickness of the electrodes, the differ ence 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.
