Personal digital assistants (PDAs) are handheld devices which are capable of performing various functions of personal computers and cellular phones depending upon the model or style of PDA. A personal digital assistant is typically comprised of a microprocessor or microcontroller coupled to a liquid crystal display (LCD) screen or display on which symbols, text or icons are displayed and, into which signals can be input and detected thereby providing a two way communications capability by which information can be stored in an retrieved from memory that is part of the personal digital assistant computer. These small, hand-held computer systems perform many of the functions that paper calendars and paper notepads used to provide, but PDAs add additional capabilities and functionality, including, but not limited to, instantaneous retrieval and display of stored information. Recently, small and compact sized global positioning satellite (GPS) receivers have also became more popular. One trend of a combined use of these devices is to connect a GPS receiver with a PDA and turn it into a personal mobile navigation system. In a GPS PDA system, a GPS receiver which receives radio waves emitted from a GPS satellite, and a processing unit for decoding a received signal and carrying out an arithmetic operation for calculating position information are provided as one integrated structure. An antenna for receiving a radio wave emitted from the GPS satellite is contained in the GPS receiver.
