Chipless substrate integrated waveguide tag using time domain reflectometry technique for millimeter wave identification (MMID)
In this paper, an equalization method is proposed in order to maximize the number of encoded bits in Time domain reflectometry (TDR) tags. In connection of used transmission line type and anticipated range of the TDR system, the dimensioning of a tag (maximum number of bits, time delay, etc) can be defined. Based on the power budget of a whole working system, Minimum Detectable Power (MDP) is set up. Substrate integrated waveguide (SIW) technology is used to build a class of chipless millimeter wave identification (MMID) tag working at 35 GHz. The proposed MMID tag is studied theoretically and experimentally in this work. The designed SIW tag comprises of 4 symmetrical iris in H plane with integrated slot antenna. The 4 bits tag is tested to demonstrate the proposed concept.
