| description | As the population of electrical vehicles (EV) in Singapore has significantly
increased these few years, large number of EV chargers are required to install to
provide the facility for EV drivers. Managing big stock of EV chargers with circular
nozzle is a challenging task for the supplier. An UHF RFID tag antenna like patch
antenna is usually constructed with a substrate and a ground plate. The ground plate
material is copper, and the substrate material is FR4, both materials have a limitation
of the flexibility to be attached on an object with a circular surface. However, PET
substrate with high flexibility in physical shape is considered in the proposed tag
antenna design.
In this FYP, the objective is to design a low cost, flexible in shape and compact size
UHF tag antenna with desirable performance in terms of return loss as well as read
range. High compactness for the overall physical size of the proposed tag design has
been achieved using a popular meander line technique. The tag antenna has been
designed, simulated and analysed by using ANSYS HFSS student version software.
Behaviour of the tag design in planar and in conformal was studied. Attaching the tag
design to the cylindrical object made of polypropylene was analysed.
Finally, the proposed tag antenna has been fabricated and S-parameters
measurement was completed on the tag prototype by using 2-ports Vector Network
Analyzer(VNA) with a test fixture. The read range of the tag prototype with a RFID
microchip soldered on the antenna has been measured with a UHF RFID reader in
the NTU Communication Research lab II located at S2-B3C-26. |
