Abstract
A quadrifilar helix antenna comprises a flexible substrate, four conductive elements with a feed network etched on a first portion of the flexible substrate, parasitic metallic lines etched on a second portion of the flexible substrate and a ground plane for the feed network. The resulting antenna structure is capable of efficiently receiving both satellite and terrestrial SDARS (Satellite digital audio radio service) signals.
