I need to prove that my antenna has 45 and -45 degree polarization from the comparison of Etheta and Ephi that have to have 1 for 45 degree and -1 for -45 degree. And I have to prove that the phase difference in 45 degree is 0 and in -45 degree is 180 from CST. I have the electrical field pattern show the 45 and -45 degree but I also need to prove it with quantitative value. Tks
