Antenna

An apparatus comprising

• a first multi-port antenna wherein the 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 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 each port of a pair of ports;
• 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.
