LOW-PROFILE PLATFORM-TOLERANT RFID TAG WITH ARTIFICIAL MAGNETIC CONDUCTOR (AMC)

摘要

A novel low-profile (≈0.01λ) platform-tolerant passive RFID tag incorporated with artificial magnetic conductor (AMC) is proposed in this letter. It consists of a modified dipole antenna combined with an AMC ground plane and a tag chip attached on the feeding point of the antenna. The proposed tag shows long and stable read range from 4 to 6 m with a realized gain ranging from 4.1 to 5.3 dB for different platform materials such as metals and lossy liquids.
