actually RFID works on 860-960MHz band, and we know its reactive part of conductivity is sensitive at THz, but i want that frequency shifting due to change in resistivity of graphene at this RFID band, so is it possible ?
Dear Dinesh,
welcome,
You can make spiral antennas on flexible materials from multilayer graphine. For the details of the antenna construction please follow the paper in the link:Article Application of graphene-based flexible antennas in consumer ...

thankyou sir,
sir, i want to use its variable conductivity property with applied potential, so that i can shift operating frequency.
is it possible? my question is that at this particular ferq. band, that shift will happen or not?
Dear Mr. Dinesh kumar Jangid,
you can change the operating frequency with an hybrid material of graphit and ferrite. With the implementation of a ferrite particle you can change the resonance frequency of the material and of the RFID tag.
I think this is a interesting hard way of a new design.
Sincerely Yours
F. Gräbner
I think you can use graphine transistors to control the dimensions of the antenna to make it a multi resonant antenna as hinted by Frank but with other technique rather than using fer rite material.
For using the graphine transistor as a switch please follow the link:https://arxiv.org/ftp/arxiv/papers/1101/1101.4383.pdf
