Abstract

An in-built antenna is provided for a mobile phone or other communication device having a main printed circuit board contained within a case, wherein components for transmitting and receiving radio signals are mounted on the main circuit board. An antenna pattern or radiator is etched on the printed circuit board surface mounting the components, in electrical connection with the components, using the same process employed to form the components and connections between them. A ground plane is mounted to the opposing surface of the main printed circuit board, in facing, spaced-apart parallel relationship with the antenna pattern and in spaced-apart parallel relationship with the main printed circuit board.
