1. An integrated circuit (IC) comprises:
- a first radio frequency (RF) section coupled to;
convert a first inbound RF signal into a first inbound symbol stream when enabled; and
convert a first outbound symbol stream into a first outbound RF signal when enabled;
a second RF section coupled to;
convert a second inbound RF signal into a second inbound symbol stream when enabled; and
convert a second outbound symbol stream into a second outbound RF signal when enabled; and
antenna coupling matrix coupled to;
in a first mode, couple the first RI section to a first antenna structure and couple the second RF section to a second antenna structure;
in a second mode, couple the first RF section to the first antenna structure and to the second antenna structure; and
in a third mode, couple the second RF section to the first antenna structure and to the second antenna structure.

Abstract
An integrated circuit includes a first RF section, a second RF section, a baseband section, and an antenna coupling matrix. The antenna coupling matrix is coupled to: in a first mode, couple the first RF section to a first antenna structure and couple the second RF section to a second antenna structure; in a second mode, couple the first RF section to the first antenna structure and to the second antenna structure; and in a third mode, couple the second RF section to the first antenna structure and to the second antenna structure.
