ABSTRACT:
A switch assembly selectively couples an antenna communication circuit to a first feed point of a first antenna, and selectively couples the antenna communication circuit to a second feed point of a second antenna. Each feed point is selected based on polarization of an electromagnetic wave to be radiated from or received by the corresponding antenna.
