The conventional design of the dual-frequency antenna used in the RFID industry at present is to use a colorless and transparent PET film as an antenna main substrate, adhere an aluminum foil on the colorless and transparent PET film through glue, and then manufacture the antenna through processes of printing, etching and the like.
The main drawbacks of this process are:
1. the RFID dual-frequency antenna can realize the information data reading of two frequency bands of high frequency and ultrahigh frequency, and the dual-frequency reading design of the RFID dual-frequency antenna brings convenient management and causes dual risks of information reading leakage.
2. The dual-frequency antenna using the PET as the carrier can be perfectly separated from the real product again in the using process due to the non-fragility of the PET material, so that the dual-frequency antenna can be reused, and the functions of substantial anti-counterfeiting and tracing of the product cannot be achieved.
