Claim 9:
10. An apparatus comprising:
a first multi-port antenna wherein the first multi-port antenna operates with a first radiation pattern when a first port is used and operates with a second radiation pattern, different to the first radiation pattern, when a second port, different to the first port, is used;
a second multi-port antenna wherein the second multi-port antenna operates with a third radiation pattern when a third port is used and operates with a fourth radiation pattern, different to the third radiation pattern, when a fourth port, different to the third port, is used; and
at least one switch for selecting one of multiple paths between a node and respective ports of the first multi-port antenna and the second multi-port antenna,
wherein the first multi-port antenna comprises a first antenna element coupled to the first port and a second antenna element coupled to the second port, wherein the first antenna element and the second antenna element are spaced apart and partially overlap without touching, wherein the first port provides a first indirect feed for the first antenna element that operates with the first antenna pattern and the second port provides a second indirect feed for the second antenna element that operates with the second antenna pattern, different to the first antenna pattern,
wherein each of the first antenna element and the second antenna element has a same shape and are arranged with different handedness, wherein the first antenna element is a monopole antenna element of a first length, wherein the second antenna element is a monopole antenna element of a second length, and wherein the first antenna element is bent and the second antenna element is bent.
