Claim 12:
13. 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;
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; and
an analogue signal interference cancellation circuit coupled between the node and an additional node, wherein the analogue signal interference cancellation circuit comprises:
a first coupling element associated with the node;
a second coupling element associated with the additional node; and
a phase shifter in a path between the first and second coupling elements.
