CST，Plot of Co- & Cross- Rad Pattern for Linear 45 degree Slant Polarization Antenna?

---

Dear All,
I am plotting Co- and Cross-Polarization radiation pattern for a linear 45 degree slant polarization antenna array. Following online guideline, I set the slant angle=-45 degree.

After that, in "General Tab", the value of phi should be selected as "0", "90", or "45"?
In my opinion, phi=90 is Horizontal-plane and phi=0 is Vertical-plane. Am I right? But how about phi=45 degree?

Please kindly give me your comments.
Thank you.

i want CST for my work and i havn't got it yet. can you please help me out?

,,, jianke, what looks inside this sector antenna ... ?
