RFID Spiral Antenna requirement

[aderich]

Hello Guys, I have this problem...
I need to design a rectangular antenna for a RFID antenna but I don't know any other parameters I need to calculate.
I have obtained a CST 2010 software, tried to design the rectangular antenna but I do not know what next to do with it.
I am working on 13.56MHz frequency.

Please I really need your help.
Thanks in advance.

Also, I need a guide on how to interpret the results obtained from the simulation.

Thanks in advance.
