A reconfigurable multi-output antenna (16) is disclosed comprising: one or more radiating elements (12, 14), at least two matching circuits (42, 44, 50, 52) coupled to the or each radiating element (12, 14) via e.g. a splitter (30, 32) or a duplexer; and wherein each matching circuit (42, 44, 50, 52) is associated with a separate port (38, 40, 46, 48) arranged to drive a separate resonant frequency so that the or each radiating element (12, 14) is operable to provide multiple outputs simultaneously. The resonant frequency of each output is independently controllable by each matching circuit, with good isolation with each other port, thereby offering very wide operating frequency range with simultaneous multi-independent output operations. Also described is a multi-output antenna control module for coupling to one or more radiating elements, an antenna structure and an antenna interface module. A reconfigurable multi-output antenna is disclosed comprising: one or more radiating.
