Summary:
A compact folded-loop antenna is proposed for near-field operations in the ultra-high frequency (UHF) band, which can be generated a strong and uniform magnetic field in a near-field zone of the folded-loop. The folded-loop with a one-wavelength perimeter is printed on the same side of FR4 substrate. The fabricated compact antenna with an overall size of a dimension of 50 × 50 × 0.8 mm3, achieves a reading zone of 30 × 30 mm2 with good impedance matching and uniform magnetic field distribution over the bandwidth of 919-932 MHz. The proposed antenna is suitable for handheld radio frequency identification (RFID) reader applications.
