Abstract
A antenna is described including a first frame having a first loop antenna element disposed thereon; a second frame having a second loop antenna element disposed thereon, the second frame disposed perpendicular to the first frame in an operational mode and disposed parallel to the first frame when in a stored mode; and a third frame having a third loop antenna element disposed thereon, the third frame disposed perpendicular to the first and second frame in an operational mode and disposed parallel to the first and second frame when in a stored mode.
