Re: NEC-List: Wire Radi to printed conductor?

Now that I look at this formula, I seems some what funny.

Do I interpret this correctly when I say that a 1mm wide strip can be
approximated by a wire of diameter 8mm.

This seems a bit much....

With wires that big I am going to get into wire rule violations.

I am using the Extended Thin Wire Kernel.

When I multiply my wire radii by 4, my simulations results go nuts.
I am trying to simulate a section of coplanar strip line that is forming a
Gamma match on a loaded dipole.

This match is integrated into the antenna, so it must be simulated

The separation between the 1mm traces of the CPL feed are also of the order
of 1mm, so Simulating structures separated (center to center )by less than
their width seems to be a problem.

Any takes on this problem?
