A method and apparatus for using Euclidean modulation in an antenna are disclosed. In one embodiment, a method for controlling an antenna comprises mapping a desired modulation to achievable modulation states, mapping modulation values associated with the achievable modulation states to one or more control parameters, and controlling radio frequency (RF) radiating antenna elements using the one or more control parameters to perform beam forming.

Restricted euclidean modulation

An apparatus is disclosed herein for a cylindrically fed antenna and method for using the same. In one embodiment, the antenna comprises: an antenna feed to input a cylindrical feed wave; a first layer coupled to the antenna feed and into which the feed wave propagates outwardly and concentrically from the feed; a second layer coupled to the first layer to cause the feed wave to be reflected at edges of the antenna and propagate inwardly through the second layer from the edges of the antenna; and a radio-frequency (RF) array coupled to the second layer, wherein the feed wave interacts with the RF array to generate a beam.

Dynamic polarization and coupling control from a steerable multi-layered cylindrically fed holographic antenna

An apparatus is disclosed herein for a cylindrically fed antenna and method for using the same. In one embodiment, the antenna comprises an antenna feed to input a cylindrical feed wave and a tunable slotted array coupled to the antenna feed.

Dynamic polarization and coupling control from a steerable cylindrically fed holographic antenna

Techniques and mechanisms to transmit signals with an antenna array. In an embodiment, a first signal is received at a first input of the first antenna while a second signal is received at a second input of the second antenna. A difference in phase differentials&#x2014;the phase differentials each between the first signal and the second signal&#x2014;results from propagation of the first signal and the second signal in the antenna array and from a difference between respective configurations of the first antenna and the second antenna. Each of the first antenna and the second antenna has respective emitters distributed along the length thereof. In another embodiment, the first antenna and the second antenna have different respective dielectric structures or different respective distributions of emitters.

Device, system and method to mitigate side lobes with an antenna array

A method and apparatus for impedance matching for an antenna aperture are described. In one embodiment, the antenna comprises an antenna aperture having at least one array of antenna elements operable to radiate radio frequency (RF) energy and an integrated composite stack structure coupled to the antenna aperture. The integrated composite stack structure includes a wide angle impedance matching network to provide impedance matching between the antenna aperture and free space and also puts dipole loading on antenna elements.

An antenna apparatus and method for use of the same are disclosed herein. In one embodiment, the antenna comprises a single physical antenna aperture having at least two spatially interleaved antenna arrays of antenna elements, the antenna arrays being operable independently and simultaneously at distinct frequency bands.

Combined antenna apertures allowing simultaneous multiple antenna functionality

A holographic antenna integrated with photovoltaic cells and method for use of the same are described. In one embodiment, the method for using an antenna comprises receiving position data indicative of an antenna aperture of an antenna after the antenna has been placed in a position to increase capture of solar energy by one or more photovoltaic (PV) structures integrated into a surface of the antenna aperture; and in response to the position data, electronically steering an array of antenna elements of the antenna to redirect a beam toward a satellite based on the position of the antenna while maintaining the position of the antenna for increased capture of the solar energy.

A method and apparatus for aperture segmentation are disclosed. In one embodiment, the antenna comprises an antenna feed to input a cylindrical feed wave and a physical antenna aperture coupled to the antenna feed and comprising a plurality of segments having antenna elements that form a plurality of closed concentric rings of antenna elements when combined, where the plurality of concentric rings are concentric with respect to the antenna feed.
