planar inductor pcb

Can anyone tell me where I can find any writing or formula or equation about
PLANAR INDUCTORs ?
I have a pcb with a planar inductor and I want to calculate the inductance of it.
the PCB is single Layer and the shape of it is like this :
_______
_______|
|_______
_______|

Can anyone Help me?
Thanks.

hi
check ieee circuits and systems magazine.

How can I achieve the IEEE and magazine ?

check your next university library ?

Hi
If there are not too many of printed inductances you can measure precisely and send dimensions of each, and also type of the substrate, I can recalculate it in nH. I have no better idea in this moment, except to advice you yo spend lot of time and learn to use some of sophisticated programs for that purrpose.
Best regards

give me the spec
i 'll simulate it for you and for free

Serpentine trace is an inductance reducing geometry; the inductance is less than an equal length of straight wire!

Tanuki,

You are correct, kind of, however it is very geometry dependant, as for the original poster, I've seen, somewhere on filemanager a PCB inductor calculator, I'm not too sure that this will work on a single sided board, with out a reference plane.

Skip

kaazemin,

What sort of application is this PCB used in?

Is it possible that the serpentine section is a antenna?

Otherwise a serpentine trace on single sided PCB makes little sense.

opps... almost forgot your IEEE question.

I put a word document in my personal folder here on elektroda that may interest you.

On Filemanger #1
path: /Tanuki/Inductance
File: InductanceOfWire.doc

i need a good cad for this
also but havent found a resonable one yet

is there any program to calculate it

Hi

I recall using PHILLIPS planar transformers design tools some time ago ..
Check them out!
