Abstract
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.
Claims6
An antenna system for use on unmanned underwater vehicles, comprising:
- an antenna assembly, comprising:
- a central post having a tether end and a feed end;
- a base engaged with the central post;
- and
- a plurality of arms pivotally connected to the base, wherein the antenna assembly acts as a monopole antenna;
- an aerial configured to attach to the tether end of the central post via a tether;
- and
- a UUV having a radio transceiver configured to attach to the feed end of the central post via a cable.
