Hello,in the patch bellow i have two ports which creates individual electric fields orthogonal to each other as shown bellow.
I have tried to test the polarity of each field using co and cross polarization of some reference linear polarity
From all photos we can see the electric fields is pointed to the Z-direction.(but from different side).
so given the menual menu bellow:

So looking with respect to the Antenna what is Ludwig X=1 Z=1 polarization means?
How can i vissualy imagine this situation?
Thanks.

You need to look at the radiated E-field at some distance from the antenna. The near field inside the antenna that you showed is not useful to see polarisation of radiated waves.

Hello Volker,In anechoic chamber the radiation of an antenna is govrned by the Polarizarion loss factor as shown bellow.
given the ludwig3 menu bellow where Z=1 and X=1, what is the pure vectoric definition value of L(reference antenna in the formula)?
Thanks.
