I was looking into the polarization of patch antennas (for GNSS use). I found this website (http://kempbros.github.io/antennas/Patch_Antenna_Generator/) which gives the geometry of the antenna starting from a couple of parameters (frequency, dielectric constant, etc..). From what I can see the polarization of the antenna (LHCP or RHCP) is determined by little cuts of the corners of the patch.
I found interesting that such a little change has such an impact on the characteristic of the antenna. Is there an intuitive explanation for this? (I do not have any antenna theory background)
