Another issue is: what size round element is equivalent
to the copper tape?
In general, you can use a round element with circumference equal to the
width of the tape (or half the width of the tape.. opinions vary).
I just did a bunch of models of a "tape" dipole at work where we were
comparing the results from HFSS (modeling a 1cm wide tape) and NEC2
(modeling it as a tube with radius 1mm.. 0.628 cm circumference) and
they were "pretty close".
The variations from the dielectric properties of the tube will have a
bigger effect.
