Hi everybody.
I have a few questions about the design of a 13.56 MHz magnetic loop antenna (to listen, not emit).
wavelenght is 300/13.56 = 22.12 m
With this value, how should I define antenna diameter ? Should I use ½ wavelenght, ¼ wavelenght or something else ?
And what about number of turns ? Is it possible to reduce antenna diameter using more turns ?
Finaly, how should I design the tuning capacitor ?
Thanx a lot.
