how to draw the radiation pattern in hfss (file attached)

Given the RAR compression utility is proprietary, with a closed algorithm, I am not a fan of it, and so don't use it. Yes, I know I can get a free decompressor, but I object in principle to the use of .rar files. There are plenty of good free alternatives, so why pay to compress your data?

If you can post your files in .zip, or other common format which is free, I''ll take a look.

If you only want to post a screen shot or picture, then why not make it a png or jpeg and the browser will show it.

Given plotting radiation pattern is quite a common thing to do, covered endless times in the HFSS examples, I'm a bit surprised you don't know how to do it.
