An antenna apparatus for use in space which is foldable into a small package for storage in a space vehicle. The antenna apparatus utilizes a plurality of hinged members and diagonal tapes forming parallelogram frames, two opposite sides of which are hinged at the center to fold the frames in a given plane. Similar frames are hinged on the first frames in a second plane whereby a plurality of cubes are formed when all are unfolded.

DETAILED DESCRIPTION The present invention utilizes a basic box truss structure to construct a plurality of cubic truss elements.
The cubic truss elements are arranged to form truss squares for each side of a cube.
A plurality of cubes comprising box truss elements are combined to form a collapsible structure such as a space antenna.
The cubes have foldable horizontal elements with diagonal tapes in each cube plane surface to provide rigidity when the cube is deployed.
It is one object of the present invention, therefore, to provide an improved deployable folded antenna apparatus.
It is another object of the invention to provide an improved deployable folded antenna apparatus which is foldable into a small package for storage in a space vehicle.
It is another object of the invention to provide an improved deployable folded antenna apparatus which comprises a plurality of cubic truss elements.
It is another object of the invention to provide an improved deployable folded antenna apparatus wherein diagonal tapes are utilized in each cube plane surface to provide structural rigidity when deployed.
These and other advantages, objects and features of the invention will become more apparent after considering the following description taken in conjunction with the illustrative embodiment in the accompanying drawings.
