Abstract
SAW (surface acoustic wave) tags are for passive RFID (radio frequency identification) systems. To overcome the drawbacks of current SAW RFIDs, which cannot be programmed after fabrication, we propose a technique to make the SAW ID tag programmable even after manufacturing. Control of the reflector bus-bar stub was used to change the phase of the reflected signals. The length of the bus-bar stub can be modified by line cutting using lasers and/or by connecting two lines by using conductive ink. The proposed SAW ID tag programs data and increases data capability.
