ANTENNA EMBEDDED IN A RADOME OF AN AIRCRAFT
An aircraft-mounted mobile communicator for communicating with one or more satellites or base stations is disclosed. The aircraft-mounted mobile communicator includes a radome structure and one or more antenna elements embedded within or proximate to a shell of the radome structure that maximizes an aperture of the one or more antenna elements, wherein the one or more antenna elements are configured to operate over one or more frequency bands.
1 . A method of manufacture of a mobile communicator to communicate from an aircraft to one or more satellites or base stations, the method comprising:
obtaining information defining a desired shape and size of an antenna array to comprise one or more antenna elements, the desired shape and size of the antenna array being defined based on dimensions of a radome structure to receive the antenna array,
the radome structure including a radome shell having a non-flat geometry relative to a substrate to receive the radome structure,
and the desired shape and size of the antenna array being defined to minimize a gap between the antenna array and the radome shell via the antenna array being contoured according to the non-flat radome shell, such that the antenna array exhibits the non-flat geometry relative to the substrate; and
forming the antenna array comprising the one or more antenna elements formed according to the desired shape and size.
2 . The method of claim 1 , wherein the substrate is one of a fuselage, wing, or vertical stabilizer of an aircraft.
3 . The method of claim 1 , wherein forming the antenna array comprises configuring the antenna array to operate in one or more frequency bands including at least one of a L 1 band, an L 2 band, a Ku band, a K a band, or a V band.
4 . The method of claim 1 , wherein forming the antenna array comprises configuring the antenna array to operate in one or more frequency bands including at least one of (i) 849-851 MHz and 894-896 MHz or (ii) 1,980-1,995 MHz and 2,170-2,185 MHz.
5 . The method of claim 1 , wherein the formed antenna array is configured to operate as an electronically steered antenna (ESA).
6 . The method of claim 1 , wherein the formed antenna array is configured to operate as a phased-array antenna.
7 . The method of claim 1 , wherein the formed antenna array comprises:
a first layer of conducting flexible textiles;
a second layer of non-conducting flexible textiles acting as a dielectric substrate, and
a third layer of conducting flexible textiles acting as a ground plane.
8 . The method of claim 7 , wherein the first layer further comprises one or more electrical components providing an electrical feed to the one or more antenna elements.
9 . The method of claim 1 , further comprising installing the antenna array to the radome structure by placing the antenna array between first and second structural layers of the radome structure.
10 . The method of claim 9 , further comprising curing the first and second structural layers of the radome structure.
11 . The method of claim 1 , further comprising installing the antenna array to the radome structure by placing the antenna array proximate to the radome shell.
12 . The method of claim 1 , further comprising filling the gap between the antenna array and the radome shell with a dielectric filler material.
13 . The method of claim 1 , wherein the antenna array comprises a plurality of tiles, each tile being fastened together along respective edges o the plurality of tiles.
14 . The method of claim 1 , wherein the gap is defined by a distance of no greater than 1.4 inches between each respective point of the antenna array and closest respective points of the radome shell.
15 . The method of claim 1 , further comprising operatively connecting the antenna array to a controller embedded within the radome shell or enclosed underneath the radome shell.
