description |
RFID system is to transfer data on a transponder (tag) that can be retrieved with a
transceiver by means of wireless connection. The whole operation is weather
independent and non-line-of-sight. These features for ID system overcome the
limitations of optical barcodes. RFID tags are comprised of integrated circuit (IC) and
an antenna. The IC executes all of the data processing and is powered by extracting
power from the interrogation signal transmitted by the RFID reader. The tag antenna
determines the amount of power transmitted from the reader to the tag and the reflect
signal from the tag to the reader. Nevertheless, there are no constraints on the physical
parameters of the reader’s antenna, such as being planar or small in size, these constraints
do stratify on the tags antenna. In fact, the tag miniaturizing is limited by the tag antenna
size.
This thesis reports on the design, fabrication, and measurement of Ultra High Frequency
(UHF) RFID tag antennas for 860 to 960 MHz which can be used in metallic
applications. The presented tag antennas are designed and fabricated to accomplish low
tagging costs, good performance, for tagging metallic objects.
Split-ring resonator-based tag antenna with regular ground plane was designed and
tested. In this design, a compact antenna is proposed and designed for metallic objects
UHF RFID (860-960) MHz. The antenna structure etched on polytetrafluorethylene
(PTFE) substrate. The slim antenna has been proposed with proximity coupled feeding,
two split ring structure mounted to each side of the tag chip and it is fed by two
symmetrical C-shaped resonators with outer strip lines. The antenna size is
83.7×62.8×1.57 mm3 at operating frequency. The peak gain and read range of the
antenna reached to -1.445 dBi and 0.5 m respectively when it is placed on
400×400 mm2 metallic surface. The antenna bandwidth is 20 MHz (power reflection
coefficient lower than -3 dB). This antenna introduced to fill up the need for tagging for
long range and mounted for metallic objects such as oil barrels tagging in petrol refineries
and gas cylinders Photonic band gap (PBG) structure integrated to enhance the gain. The PBG structure
formed by etching a periodic pattern of circles in the ground plane. The total gain and
read range of this design are -0.72 dBi and 0.53 m respectively when it is mounted on
400×400 mm2 metallic plate. The percent of gain improvement is around 49.76% when
PBG integrated in the design. The antenna bandwidth at half power bandwidth is 17.8
MHz. The impedance of the suggested antennas was simulated then measured to validate
the design. The presented RFID tag antennas are low cost, compact, and with good gain
that make it fit for tagging metallic applications. |
