Abstract: An electronic device includes a microprocessor connected to an input keyboard comprising primary conductive lines connected to primary areas and to a terminal. It further includes first, second and third secondary conductive lines connected to secondary areas and to a terminal. It further includes input keys each of which, when operated, establishes contact between a primary area of a primary line and a secondary area of a secondary line to place each of these two lines in a high state.

Abstract: The present invention relates to a handheld electronic communication device comprising, in a housing (1), a printed circuit board (2) for holding electrical components and providing several connection points, and a keypad (5) extending parallel to said printed circuit board (2) and including a keypad user's interface (5c), made of a metallic sheet, said device further comprising a radio communication module for transmitting and/or receiving signals, said radio communication module being connected to a radiating element via an antenna's feeding point on printed circuit board (2). According to the invention, said metallic sheet is provided with at least a connection area (5e) electrically connected to said antenna's feeding point of said printed circuit board (2), and said metallic sheet further comprises a slot (8), said keypad user's interface (5c) constituting then said radiating element whose working frequencies depend on the shape and the size of said slot.
