I need design a circularly polarized microstrip antenna. But i don't know specify phi and theta.

Currently my setup is this:
Phi = 0
Theta = -180 ~ 180
Is it correct?

por example, if I find AR < 3 for theta = -150º in my operation frequency, can i say that my antenna works in CP?

Thanks in advance and sorry for my bad english.

Sounds good to me.

It depends on your specifications. I don't know of any standards for CP, although I am not an antenna expert.
