HFSS - how can I draw a folded dipole?

I need to draw a folded dipole, which forms part of a Yagi antenna.

I thought the best way to draw the rounded ends of a folded dipole would be to start with a torus, then remove unnecessary parts. But unfortunately, the plane of the dipole is almost (but not quite) horizontal along the x axis. It is inclined a bit (about 10 degrees). So it's not exactly in line with any of the elements, which all lie in the XY plane You might argue that's not the ideal way to place a folded dipole, but that's want I want to model.

How can I best draw such a structure?

Hello DeboraHarry

I think you can draw the edges by sweeping. Draw---sweep--along path.

Let me know if you need any help

Deborah,

Please see attached file. This was a Yagi-Uda antenna array I put together for optimization but never got around to it. The Yagi_uda is driven by a folded dipole antenna which was optimized in its own design in the file for the given frequency.

Thank you. That looks interesting, but I can't quite work out how you got the arc. I can see it uses a polyline, but I'm not sure how to do it.

I've attached a simple version of what I have. I've drawn the boom, and two parts of the folded dipole. One is longer than the other as there will be a gap when the dipole is fed. I'm not sure how to link up the two ends away from the boom into an arc. Once I get that, it should be possible to mirror this about a suface which goes through the middle of the boom.

I tried Draw -> Arc, but that only draws a line, and I could fine no way to add thickness to the line.

For now I have both parts of the folded dipole on the z==0 line. Later I intend moving one part up a bit, but for simplicity I've left it like this.

Any suggestions how I can add the arc on the end of my model would be appreciated.
