Abstract

An antenna assembly which comprises a central ele­ ment extending from a support, a plurality of resilient elements extending from the suport and arranged about the central element, and retaining means for maintaining the distal ends of the resilient elements in juxtaposition to the central element, and wherein the resilient elements deploy, by bias stored therein, to operative positions about the central element when the distal ends thereof disengage the retaining means.
