Abstract
Flexible diversity antennas having gain and bandwidth capabilities suitable for use within small communications devices such as radiotelephones are provided. A core of flexible material has an electrical conductor embedded therewithin in a meandering pattern and is surrounded by a first layer of flexible dielectric material. At one end of the antenna, the first layer of dielectric material is surrounded by flexible conductive material. The flexible conductive material is surrounded by a second layer of flexible dielectric material. The portion of the antenna surrounded by conductive material serves as a tuning element, and the portion of the antenna not surrounded by conductive material serves as a radiating element. A flexible signal feed is integral with the antenna and extends outwardly from the flexible core.
