Abstract: An apparatus has a data input device arrangement and an electrical circuit. The data input device arrangement includes at least one user input key and at least two keylines configured to provide a data input to the apparatus. The electrical circuit has at least a first electrically conductive component configured to decouple the data input device arrangement at a predetermined radio frequency band to provide an antenna. In an embodiment the predetermined frequency is an operational frequency of the provided antenna. In various embodiments when the data input device is decoupled one of the keylines provides an antenna radiator component, and in another it provides an antenna parasitic short to ground. In various embodiments the first electrically conductive component exhibits a high impedance at the predetermined radio frequency band, and in another it is a notch filter which passes the predetermined radio frequency band.
