Abstract
A dual frequency identification system for animals is contained within an ear tag structure adapted to be attached to an animal's ear. The system includes a first radio frequency component having a first antenna that operates at a first frequency, and a second radio frequency component having a second antenna that operates at a second frequency higher than the first frequency. The radio frequency identification system is programmed to transmit the same identification code from both of the first and second antennas, whereby the tag can be interrogated by reader antennas operating at different frequencies to identify the same animal. Various constructions for the ear tag are disclosed in which the first and second frequency components are molded into the plastic parts of the ear tag.
