    RFID Coil design and Simulation

    hi

    I need some design application notes for RFID coils. Can i simulate coil in ADS or HFSS etc. Is there any example available for ADS momentum. Is it possible to beam forming using coil arrays?

    Regards

    What RFID frequency band? UHF?

    What I have seen for UHF RFID readers are patch antennas.

    EM simulation is possible and useful, planar simulation with ADS Momentum is a good starting point.
    A former collegue designed this using CST:

    Re: RFID Coil design and Simulation

    Freespace wavelength at 390 MHz is 77 cm. I guess you are talking about coils for near-field applications.

    Both ADS Momentum and HFSS can help for the coil design, though the former should be faster and easier in this case.

    Thanks for reply.

    Yes i am talking about near field applications.
