Method for making antenna of coaxial cable and the antenna so made

A cable antenna includes a circuit board to which first ends of two antenna cables and a coupling cable are soldered. A second end of the coupling cable forms a connector for connection with a signal receiving/transmitting circuit. Each of the antenna cables has a second free end exposed to the atmo...

Zusammenfassung:A cable antenna includes a circuit board to which first ends of two antenna cables and a coupling cable are soldered. A second end of the coupling cable forms a connector for connection with a signal receiving/transmitting circuit. Each of the antenna cables has a second free end exposed to the atmosphere for receiving/transmitting electromagnetic signals. An outer jacket of each antenna cable is removed along a first predetermined length measured from the free end thereof to expose a braided shield A second predetermined length of the braided shield measured from the free end is removed for exposing an inner dielectric layer that surrounds a core conductor. The second length is less than the first length thereby leaving a portion of the exposed braided shield on the inner dielectric layer. The braided shield that is cut from the cable is twisted to form an elongate consolidated conductor. The consolidated conductor made of the braided shield is then soldered to the portion of the exposed braided shield that is left on the inner dielectric layer thereby completing the cable antenna. Preferably, the consolidated conductor made of the braided shield is arranged to be substantially normal to a central axis of the cable. If desired, the core conductor may be bent 90 degrees off the central axis of the cable. The consolidated conductor made of the braided may be replaced by other conductive member having substantially the same length.
