A low cost, reduced complexity antenna fabrication scheme employs a section of a thin, lightweight flex circuit decal, rather than a wire, as the antenna's radiation element. In order to support and contour the flex circuit decal in a three-dimensional (e.g., helical) shape, the flex circuit is attached to a support core that conforms with the intended three-dimensional shape of the antenna. To reduce the hardware and assembly complexity of using an electro-mechanical connector to interface the antenna radiator and its associated feed, the signal coupling interface for the antenna is effected by electromagnetically coupling of a segment of the flex circuit to a section of transmission line spatially located in close proximity to the antenna.
