ABSTRACT:
A flexible feed line is provided for use with a selectively deployable antenna system. The feed line is resilient and expandable so that it can maintain connections within antenna feed circuits while the antenna is being deformed or moved for stowage. An antenna system for use with the feed lines of the present invention may consist of a deployable quadrifilar helical antenna elements having four resilient conductive strips bonded thereto. Flexible feed lines are attached to each of the conductive helical strips. The feed lines expand to accommodate the shape of the antenna elements when compressed for stowing and return to their operating shape when deployed, thus providing identical feed paths to each of the antenna conductors when the antenna system is deployed.
