A Passive RFID Tag Antenna Installed in a Recessed Cavity in a Metallic Platform

  title={A Passive RFID Tag Antenna Installed in a Recessed Cavity in a Metallic Platform},
  author={Dongho Kim and Junho Yeo},
  journal={IEEE Transactions on Antennas and Propagation},
A passive RFID tag antenna in a recessed cavity in metallic objects such as vehicles, air craft, and metallic containers, and an impedance matching technique for this configuration are proposed. The proposed tag antenna can be considered as a cavity-backed antenna and it is comprised of a bowtie antenna installed in a recessed cubic volume in a large metallic object, and the input impedance of the bowtie antenna can be easily matched by adjusting the coupling effect between the tag antenna and… CONTINUE READING
