I am trying to use meander shape coil on PCB for wireless power transfer, with no luck so far. The primary coil is meander shape on PCB, receiving coil is a loop of wire with a tuning cap. Both RLC circuits tuned for 740Khz.I would like to induce at least 0.5V at 1cm. I have successfully resonantly coupled secondary coil with THT drum coil I only have a problem with PCB coil.
Can I connect another inductor in series with primary coil to increase its inductance and will it affect electromagnetic field around PCB coil?
How to make electromagnetic field stronger on PCB coil other than increasing current?
When designing meander PCB coil is it better to make more turns, less spacing between them and thinner lines or wide lines and bigger spacing?
Does higher inductance mean bigger field surrounding coil?
Should Both RLC circuit be impedance matched and how crucial it is?
