The system for a collapsible direction finding antenna. The antenna comprising a rigid central portion and a plurality of foldable arms. The antenna is aerial/kite lifted once launched from a tube to provide increased line of sight above a surface. The antennas being launchable from a UUV, a user in the field, and the like. The antenna being a full azimuth direction finding antenna. In some cases, operating at a wide matched frequency of 1 to 6 GHz.

Collapsible direction finding antenna array for space-disadvantaged cylindrical platforms

The system for an antenna assembly for use on unmanned underwater vehicles (UUV). The antennas are low-cost, lightweight, single-use, and have a small form factor amenable to use on a micro-UUV. A central post and pivotally attached arms form an antenna (e.g., a monopole) that is lifted via an aerial, kite, or the like, when deployed from the UUV to extend the line of site of the antenna several meters above the surface of the water. In some cases, the antenna may be used on a number of UUVs in a swarm formation.
