A half wavelength at that frequency is about 10 meters. Hard to fold that
up in a small tag. Figure all dimensions are 1000X when translating from
microwaves to HF.

Hello to everybody,
first of all I say sorry for my bad English and for my really bad
knowledge.
I'm projecting an antenna for RFID (13.56 MHz) and I don't know if is
possible to use a strip line with this frequency.
I've seen that in some books there are some theory equations regarding
GHz,
but nothing about Mhz.
Is the wavelenght too long compare to the dimension of a stripline?
Thank you,

Massimo
