摘要
A novel low-profile broadband UHF RFID tag antenna with two parasitic patches is proposed. The tag antenna's bandwidth can be greatly enhanced by adding parasitic patches which are gap coupled to the driven patch for the excitation of additional resonant modes. The half-power bandwidth of the proposed antenna covers all the UHF RFID frequency bands, and the power reflection coefficient is lower than -7dB in the UHF RFID frequency bands (840-960 MHz). The proposed antenna can be easily fabricated at low cost by etching at a thin inexpensive FR4 substrate.
