Abstract
A device comprises a conductive casing and a radio device located inside the casing. A pair of wires run from the radio device to an opening in the casing, wherein at least one of the wires carries a signal from or to the radio device. The pair of wires pass through the opening and are configured such that inside the casing they function as a transmission line and outside the casing, they are formed into an antenna. In one embodiment, one of the wires is a ground wire and the other is a live wire and, outside the casing the ground wire terminates and the live wire extends to form a monopole antenna. In another embodiment, both wires carry the signal and function as a balanced transmission line, and outside the casing the wires are separated and form a dipole antenna.
