Hello, Axial ratio is defined as the ratio between amplitude of one component of electric field and another component of electric field.
But this definition doesnt take into account the phase between them.
So technically if we have X-axes and Y-axes components withe the same amplitude and zero phase between them,then by the Axial ratio formula we will have 0dB as if its a circular polarization.
Where am i wrong in my logic?
