Semi-conductor Applications to Printed Circuits on Flexible Surfaces

The most common type of identification system today is RFID. RFID circuits are used as covered with plastic. With the increase in usage areas, it also on metal, wood, paper, and plastic product. In this study, behavior same circuit different surfaces was investigated. surface impedance signal reflection coefficients tag antennas were investigated based plastic, textile surfaces. According to results electrical mechanical tests, best terms reflectance impedances tags PET high paper lowest values measured results, has been seen that antenna application possible usable.
