I'm working on an RFID project, and looking for information about the antennas that I have to use, I have the following doubt: Antenna polarization and antenna directiivity are the same? Thanks!

Polarization refers to the relative angles of the electric and magnetic fields along the path of propagation.

Directivity refers to the gain of the antenna at various angles relative to its own axis.
