A planar wideband microstrip patch antenna for UHF RFID tag
In this research, a planar wideband microstrip patch antenna for passive radio frequency identification (RFID) tag is proposed. To enable universal operation by covering the operating frequency of ultra-high frequency (UHF) RFID band from 860 MHz to 960 MHz, two C-shaped patches are employed. B...

| Summary: | In this research, a planar wideband microstrip patch
antenna for passive radio frequency identification (RFID) tag is
proposed. To enable universal operation by covering the
operating frequency of ultra-high frequency (UHF) RFID band
from 860 MHz to 960 MHz, two C-shaped patches are employed.
Both of the patches are inductively coupled fed by a rectangular
loop feeding network for complex impedance matching with the
referenced microchip impedance. The proposed antenna is
designed for tagging metallic objects. To simplify the fabrication
process and to reduce cost, a planar antenna structure is chosen
over multi or cross layered configuration. The simulation and
measurement results show impedance bandwidth of 159 MHz and
155 MHz (Return loss
≥
3 dB) respectively when mounted on
metal plate. |
