Abstract: The present application describes an antenna assembly. The antenna assembly includes a cable including a jacket surrounding an internal conductor.

Abstract: The present application describes a method of forming a flexible dipole antenna. The method includes a step of surrounding an outer jacket of a cable with a lower limit radiating element. The lower limit radiating element includes a first annular surface opposite a second annular surface with a hollow body disposed therebetween joining the first and second annular surfaces together. Each of the first and second annular surfaces has a diameter greater than a diameter of the outer jacket of the cable. The method also includes a step of extending a bandwidth of the flexible dipole antenna by indirectly surrounding the lower limit radiating element with a higher limit radiating element. The higher limit radiating element has a length approximately 30% less than a length of the lower limit radiating element, allowing the higher limit radiating element to capture frequencies greater than those captured by the lower limit radiating element.

The metallic shield encases an internal conductor of the cable. The method further includes a step of encasing the cable and the lower limit radiating element in a flexible outer sheath having a first end opposite a second end with a hollow body disposed therebetween joining the first and second ends together.

Abstract: A broadband antenna assembly including a coaxial cable, a lower limit radiating element, a higher limit radiating element, and a flexible outer sheath encasing the components of the assembly. The lower limit radiating element has a diameter greater than a diameter of an outer jacket of the coaxial cable, allowing the lower limit radiating element to surround the coaxial cable. The dipole formed by the lower limit radiating element is approximately ? of the wavelength of the lower limit operating frequency. To capture higher frequencies, the higher limit radiating element includes a dipole that is approximately 30% shorter than that of the lower limit radiating element, allowing the antenna assembly to capture a wider bandwidth. By providing the radiating elements together with the coaxial cable, the antenna assembly removes the need for adapters and separately-connected component parts while providing a flexible outer sheath, improving mobile broadcasting applications.
