1. A self-erecting antenna having separate stored and erected states and comprising:
- a central base;
a single unarticulated antenna support member pivotally mounted to the base and foldable with respect to it when the antenna is in a stored state;
at least one antenna element integrally formed with the antenna support member;
at least one sheet of spring-biased flexible material connected along a first edge to the base and along an opposite edge to the antenna support member the central sheet area therebetween being free of connection, the antenna support member and the antenna element connected thereto self erecting when externally applied forces normally biasing the support member and connected element in a folded position are removed.

Abstract
A self-erecting antenna includes a base for pivotally mounting two oppositely extending pi-shaped dipole antennas that are symmetrically positioned with respect to a medial ground plane attached to the base. Two sheets of flexible KAPTON material are each connected at opposite edges thereof, between the base and a respective dipole antenna, enabling collapsed folding of the antenna for storage. When the dipole antenna is free to move, the KAPTON sheets act like springs to erect the dipole antenna to a deployed condition.

6. A self-erecting antenna comprising:
-
a central base; an antenna support member pivotally mounted to the base and foldable with respect to it; at least one antenna element connected to the antenna support member; at least one sheet of flexible material connected between the base and the antenna support member for protecting the antenna from entanglements with adjacent antennas, and for erecting the antenna support member and the antennas element connected thereto, when externally applied forces normally biasing the support member and connected element in a folded position are removed; wherein the antenna support member is a substantially rigid, generally pi-shaped member having a horizontal section for attaching the antenna element; and vertical spaced legs extending perpendicular to the horizontal section, the legs being pivotally mounted to the base.

7. A self-erecting antenna comprising:
-
an annular base; a flexible ground plane member mounted to the base; a pair of rigid parallel legs pivotally mounted to the base and extending on opposite sides of the ground plane; a first antenna support member, attaching a dipole antenna conductor, and connected across adjacent first ends of the parallel legs; a second antenna support member attaching a dipole antenna conductor and connected across adjacent second ends of the parallel legs; first and second sheets of flexible material respectively connected between the base and the first and second support members for erecting the antenna support member and the antenna conductor attached thereto when forces biasing the sheets in the folded position are removed. - View Dependent Claims (8, 9)
