Hi all,
I try to design a loop antenna to read my chipless RFID tag. The frequency range is from 150MHz to 280MHz. After using the formula of loop antenna, i get a loop antenna circumference at 1.61m, radius of loop at 0.256m, radius of the wire at 4mm and single turn.
The loop antenna is very big compare to my tag which dimension is 48 x 47 mm. Is that mean antenna is too big to read my tag?
Besides that, does anyone know how to calculate the bandwidth of loop antenna above ?
Thanks!
