Methods and systems of changing antenna polarization. At least some of the illustrative embodiments are systems comprising an antenna having a first feed point and a second feed point, an antenna communication circuit, and a switch assembly that selectively couples the antenna communication circuit to the first feed point, and that selectively couples the antenna communication circuit to the second feed point. The feed point (or group of feed points) is selected, for example, based on polarization of an electromagnetic wave to be radiated from or received by the antenna.
