Portable Pop-up Direction Finding Antenna

Abstract: 

An easily transportable multiband antenna array. The antenna array is fabricated on a multi-sided structure, such as a four-sided cube, made from a wire frame and fabric. The multi-sided structure is constructed so that it may be folded by first folding the faces against each other, and then twisting them to form a stack of loops. The antenna elements are fabricated on the faces, and comprise at least a loop antenna around the perimeter of each face, and a bow-tie antenna attached to each face. The antenna elements are fabricated and attached so that they do not inhibit the folding of the structure.
