Abstract
This invention relates to internal antenna arrangements for radio communications handsets. Internal antenna size and shape represents a constraint on handset miniaturisation if good antenna efficiency and bandwidth characteristics are to be maintained. The use of acoustic enhancing volumes of free space about a handset's speaker unit also constrains further miniaturisation. The present invention provides an internal antenna arrangement which facilities further miniaturisation and which combines antenna volume with the acoustic enhancing volume.
