    Abstract: A method of manufacturing a dipole antenna comprises the steps of forming first and second radiating elements on the surface of a flexible substrate, the radiating elements including respective feed points for making operative electrical contact with a feed line including corresponding first and second feed conductors. The radiating elements are arranged on the substrate such that, in use, an input impedance of the dipole antenna is substantially matched to a characteristic impedance of the feed line over a selected frequency band. The flexible substrate is then formed into a substantially cylindrical shape. The resulting antenna comprises an integral dipole antenna member having radiating elements disposed on a surface of a substantially cylindrical substrate. The antenna avoids the need to separately manufacture the radiating elements, and subsequently to assemble the elements to form a dipole antenna.
