| Summary: | The chipless resonator tags are at the forefront
of the conventional barcode replacement research. The tag is
still larger in dimension and a matter of concern for the
researchers. The resonator tag comprised with two separate
antennas working as Tx and Rx, one transmission line and
resonators. The resonators have various types of shapes.
Recently one rectangular resonator tag is proposed for UWB
RFID detection. Here one study is performed to compare the
rectangular spiral with the circular spiral to see the effect in
terms of space reduction. One rectangular spiral and one
circular spiral at the same resonance frequency (2.5GHz) are
designed in CST MWS. The result shows a reduction in area of
9.8% while using circular resonator instead of rectangular
resonator but with the cost of wideness of the bandwidth. |
