[Antenna][Drawing tip requested] Stacking 2 spiral inductors for enhacing inductance

Hi,

I am just asking myself if it is possible to stack 2 planar circular spiral inductors, with respect of the current direction, and with the minimum overlay.
If I start from the outside of the first coil to the center, and switch from this first coil to the other, the current flows the opposite direction, so I guess the inductor will suffer for this problem?

Do you have some advices ?
Thanks for your help

Draw the inductor so that turns on both layers follow the same direction.

hi
i think this work not useful for antenna dont try it

If "antenna" is an RFID tag with inductive coupling - why not?

thats true it can work for narrow band application but it too expensive for RFID
