I am now designing a circularly polarized antenna by couple a rectangular microstrip antenna with a 3dB branch-line coupler. As i am designing in MOMENTUM, i look at the 2D plot to check whether it is circularly polarized or not.
However, I am not so sure whether the result is ok or not.
I wish to ask whether anyone know how to see the result?
Is it I need to see the axial ratio?
