Abstract :
This letter presents a novel tag structure for microwave identification. The new tag is based on a high quality factor (Q=366) substrate integrated cavity resonator in which data are encoded by introducing a variation in the effective permittivity which gives a unique and identifiable frequency spectral signature. The proposed tag design operates in the frequency range of 10.5-11 GHz. The substrate integrated tag presented has the advantages of being low cost, zero power consumption, compact and can be also transferred to different types of substrates, making it suitable for many mass production applications.
