Abstract: A radio communications device, such as a mobile phone or Bluetooth device, comprises a ground conductor (302) incorporating a slot (304) and means (308) for coupling a transceiver to the slot to enable the ground conductor to function as an antenna. Such a device enables efficient radiating performance to be obtained from a significantly smaller volume than known antenna arrangements. In one embodiment the ground conductor (302), slot (304) and transceiver are integrated in a module (206), which module is adapted for connection to a further ground conductor which provides the majority of the antenna area. The further conductor would typically be a printed circuit board ground plane or mobile phone handset. Matching and broadbanding circuitry may conveniently be incorporated in the module. By varying the area of the connections between the module and the further ground conductor, the resonant frequency of the slot (304) can be modified.
