Hello all, I'm working with the rc522 rfid reader for a project. However the range of rc522 is only about 4-5 inches. I want read range of about 1 metre. I have read about a method to increase the range by connecting an antenna to the output of rc522. But I'm unable to implement the antenna design properly. Is there any other method to increase the read range? Or please suggest me a design procedure for the antenna.
