Abstract
A long-distance radio frequency anti-metal identification tag is provided. When a bottom surface of an insulating spacer plate is attached to the surface of a metal object and an electronic tag reading device is used to read a radio frequency identification chip on a second antenna. A resonant cavity is formed between a slot of a first antenna and the surface of the metal object through the isolation of the insulating spacer plate, such that the second antenna located at the position of the resonant cavity resonates with an electromagnetic wave signal reflected on the surface of the metal object by the first antenna. The electromagnetic wave signal is transmitted to the radio frequency identification chip, or the feedback signal of the radio frequency identification chip is transmitted out. The overall UHF electronic tag is resistant to a metal interference and has the performance of long-distance reading.
