Abstract
Provided is a collapsible antenna formed of one or more generally planar and vertically inclined inflatable panels. According to the invention, each of the panels has a continuous outer wall, a continuous inner wall and a plurality of web partitions extending between the inner and outer walls to form a series of tubular members. The inner wall of the collapsible antenna is at least partially covered by a metallic material and a plurality of dipole elements are affixed to the web partitions and spaced from the inner wall in a predetermined relationship such that the antenna will operate at a preselected frequency when inflated.
