Desiging Rfid reader

  1. Jan 14, 2010 #1
    Hi to all, I am looking for suggestions and help

    I already have Rsk board (TRH031M reader for 13.56MHz rfid, ISO 14442A)

    i am planing to design or build a Rfid reader using RFID tags(ISO 14442A).

    I am looking at building the small transformer that links rfid reader. I need some suggestion and ideas...........!

    When you say transformer, do you mean the antenna?

    TRH031M info (some in Korean) http://www.3alogics.com/

    Google search on 13.56MHz RFID antenna: http://www.google.com/search?hl=en&...ved=0CA0QBSgA&q=13.56MHz+rfid+antenna&spell=1

    Thanks for the reply, well i need to relate the transformer to make reader. why the coupling of a passive HF-RFID tag can fundamentally be modelled using transformer theory

    Aim of the mini project is to design a reader that detects the 13.56 Mhz tags by simple transformer theory

    Have you read the link in my post #3? Do you have any specific questions about it?

    Well, it was the usefull information.. now i need to design a antenna coil, which should make up resonance frequency 13.56 MHz. if possible can you suggest any site or design.. to make antenna coils.

    Have you read through the Google search hit list that I posted in Post #2? There appeared to be a number of useful sites.
