Abstract
A method and apparatus for reducing a length of an antenna () involves an arrangement which includes an orthogonal antenna feed. An antenna includes a radiating element () with a length extending along an axis (). The orthogonal feed arrangement permits recovery of a portion of the spatial volume comprising the antenna which is normally used for antenna matching circuitry (). An end portion of the radiating element is chosen to be helically shaped and includes an RF feed gap. The RF feed gap is coupled to a matching network which includes elongated conductors (). The matching circuitry is positioned so that the elongated conductors are adjacent to the first end portion and extend in a direction aligned with the axis, but orthogonal to the coils forming the helically shaped end portion.
