Long-Range Miniaturized Ceramic RFID Tags

Radio frequency identification (RFID) is a mature technology, which allows performing contactless data readout via wireless communication links. While protocols in this field are subject to regulations, there room of opportunities improve the hardware realization antennas devices, support technology. In particular, range extension and miniaturization passive RFID tags an important objective with far going impact on retail, security, IoT, many others. Here we introduce new concept high-permittivity ceramic tag, relies different physical principles. Instead using conduction currents metallic wires drive electronic chips radiate electromagnetic waves, high permittivity components rely efficient excitation displacement currents. Those efficiently converted currents, powering memory chip. The practical aspect approach improved robustness environmental fluctuations, footprint reduction, extension. our ({\epsilon} ~ 100) elements have demonstrated 25% reading improvement respect commercial tags. case, when state art readers used, distances developed approaching 23 m could be further extended matching circuits.
