Abstract
A deployable antenna assembly includes a canister providing an elongated mber and an elongated hollow mast with a mounting member on its upper end. A coaxial cable extends into the hollow mast to provide radio signals to the antenna assembly of four antenna members of resiliently deflectable members spaced at 90 degree intervals about the periphery of a mounting plate. In the non-deployed position elongated arms extend downward along the inner wall of a canister. A resonant circuit having an inductive coil and a capacitor are located at an intermediate position on the arms. A smooth material is placed between the resonant circuit and the wall of the canister to prevent scraping and damage to the resonant circuit upon deployment. Each opposed pair of antenna element comprises a dipole. A pair of baluns are formed by the arrangement of coaxial cable. A hybrid circuit forming a phase shifter is securely affixed to a mounting plate.
