A Low Profile and High Read Range Slotted Antenna for Dual-Band Anti-Metal UHF RFID Tag Antenna
A single-layer, compact tag antenna with 50 × 50 × 0.857 mm3 dimensions is proposed for dual-band anti-metal applications. A U-shaped feeding loop is employed to excite the fundamental mode of the tag antenna, while an orthogonally placed parasitic patch generates an additional frequency band. This...
