Abstract
In some embodiments, an antenna may include a plurality of reflectarray tiles and a frame including a plurality of frame elements coupled electrically and mechanically. The frame may be configured to conform to a shape of a surface. Each frame element may be configured to receive one of the plurality of reflectarray tiles. In some aspects, the plurality of reflectarray tiles may be illuminated directly or indirectly by a feed.
Claims20
An apparatus comprising:
- a plurality of reflectarray tiles;
- and
- a frame including a plurality of frame elements, each frame element including a frame coupling interface configured to electrically and mechanically couple the frame element to one or more adjacent frame elements, the plurality of frame elements configured to couple to an exterior surface of an aircraft or a terrestrial vehicle and to conform to a shape of the exterior surface, each frame element including a recessed portion inset from a sidewall of the frame element and configured to receive one of the plurality of reflectarray tiles, the frame provides mechanical registration and alignment to a known physical geometry, each frame element of the plurality of frame elements includes wiring to communicatively couple each reflectarray tile to a control system to receive power via a power bus and to receive signals via one or more electrical interconnects to control a phase reflection of the reflectarray tile;
- and
- wherein each of the plurality of frame elements is modular such that one or more selected frame elements may be added to or removed from the frame to correspond to the plurality of reflectarray tiles.

An apparatus comprising:
- a frame including a plurality of frame elements, each frame element including a frame coupling interface configured to electrically and mechanically couple the frame element to one or more adjacent frame elements to form the frame, the plurality of frame elements conforming to a shape of an exterior surface of an aircraft or a terrestrial vehicle, each of the plurality of frame elements including a recessed portion, each frame element of the plurality of frame elements including electrical interconnects to provide power and signals from a control system to an associated reflectarray tile;
- and
- a plurality of reflectarray tiles, each reflectarray tile sized to couple to one of the plurality of frame elements and to engage the recessed portion and the electrical interconnects, the plurality of reflectarray tiles configured to couple to the plurality of frame elements to form a conformal reflectarray, each reflectarray tile of the plurality of reflectarray tiles responsive to the signals received from the control system via the electrical interconnects of the frame element to adjust a phase reflection of the reflectarray tile;
- and
- wherein each frame element of the plurality of frame elements is modular such that selected frame elements may be added or removed from the frame to accommodate a selected number of reflectarray tiles.

- and
- an illumination source configured to illuminate at least a portion of the conformal reflectarray;
- and
- wherein each frame element of the plurality of frame elements is modular such that selected frame elements may be added to or removed from the frame to accommodate a selected number of reflectarray tiles.
