ok. Here we go again, range of the Phi variable doesnt have anything to do with co and cross polarization, i was talking about setting up the radiation sphere. how would you draw a sphere by integrating two circles right? how many degrees do you have in each circle 360 degrees?
coming back to your question about co and cross polarization. co polarization is the polarization that you are intending and cross polarization is the orthogonal polarization to the intended polarization. for instance let's say your antenna is vertically polarized(co polarization) what would be the cross polarization? horizontal polarization(right) which plane does it fall into?
yes you are right when you check for cross and co polarization, you are looking at their values in each plane.
How do you investigate the polarization of your antenna by checking for the axial ratio.
