| Summary: | A planar wideband patch antenna for ultra�high
frequency (UHF) radio frequency identification (RFI
D) tag for
metallic applications is presented in this research
work. Three
different shape patches are inductively coupled to
a triangle loop
to excite three resonances close to each other to f
orm wide
impedance bandwidth for universal application UHF (
860�960
MHz) RFID. The structure of the proposed antenna ex
hibits
planar profile to provide ease of fabrication for c
ost reduction
well suited for mass production. The simulation of
the antenna
was carried out using Finite Element Method (FEM) b
ased
software, Ansoft HFSS v13. The performance of the d
esign was
verified by the simulation and measurement results
which show
good agreement. The simulated and measured impedanc
e
bandwidth of 113 MHz and 117 MHz (return loss ≥ 6 d
B) was
achieved to cover the entire UHF RFID operating fre
quency band
worldwide. |
