Selectively coupling to feed points of an antenna system. At least some of the illustrative embodiments are systems comprising an antenna system, an antenna communication circuit, a first diode coupled between the antenna communication circuit and a first feed point of the antenna system, and a second diode coupled between the antenna communication circuit and a second feed point of the antenna system. The antenna communication circuit is configured to couple the antenna communication circuit to the first and second feed points by forward biasing the diodes.
