Conformal antennas for unmanned and piloted vehicles and method of antenna operation
View Patent ↗A vehicle includes a body providing structural support and defining a fuselage perimeter and including a plurality of bands, a plurality of antennas integrated into the plurality of bands, and a transceiver operatively connected to each of the plurality of antennas. The transceiver is configured to power selected sub-sets of the plurality of antennas to generate a directional antenna beam.
1. A vehicle comprising:
a body providing structural support and defining a fuselage perimeter, wherein the body includes a plurality of annular bands that are separated axially along a primary axis of the body and distributed axially across substantially the entirety of the fuselage perimeter, wherein the plurality of bands conform to a shape of the perimeter;
a plurality of antennas integrated into the plurality of bands, each antenna conforming to the shape of the perimeter along a corresponding band; and
a transceiver operatively connected to each of the plurality of antennas, the transceiver configured to power selected sub-sets of the plurality of antennas to generate a directional antenna beam,
wherein multiple ones of the plurality of antennas are located on and distributed across a single layer of each of the plurality of bands, the antennas on a given one of the plurality of bands separated from adjacent antennas in the single layer by electrically insulating material.
2. The vehicle of claim 1 , wherein each of the plurality of antennas comprises a patch antenna.
3. The vehicle of claim 1 , wherein each of the plurality of bands comprises:
a ground plane;
a layer of dielectric material adjacent to the ground plane; and
a first patch antenna tile on the layer of dielectric material and opposite the ground plane, the patch antenna tile forming one of the plurality of antennas.
4. The vehicle of claim 3 , each of the plurality of bands further comprising:
a second patch antenna tile on the layer of dielectric material and opposite the ground plane, wherein the second patch antenna tile is separated from the first patch antenna tile by an electrically insulating material.
5. The vehicle of claim 1 , wherein at least one of the plurality of bands comprises interlocking tiles of composite material having integral coupling structures.
6. The vehicle of claim 1 , wherein the body comprises a fuselage of an aircraft.
