To avoid performance fluctuation of radio frequency identification (RFID) system while the tag is attached on objects with different materials, a platform-tolerant UHF RFID tag antenna with stable high gain is proposed in this paper. The antenna is composed of an upper layer feeding loop and a lower layer planar dipole. Inductively coupling approach is adopted to feed, so that large mutual inductance...
A low-profile ultra high frequency (UHF) radio frequency identification (RFID) tag antenna is proposed with a compact size of 80 × 30mm2 and stable gain while attaching on different mediums. The antenna is composed of a quarter-wave length patch etching on FR4 substrate and a suspended inductively coupling loop who connected with a RFID chip. The antenna acts as an omnidirectional electric monopole...
