The present invention is related to means for elimination of antenna orientation errors in millimeter wave point-to-point communication systems with beam steerable antennas. The advantage of the proposed method consists in accelerating antenna angular orientation adjustment for two connected transceivers. The advantage is achieved via determination of a value and a direction of an antenna orientation error and its further fast mechanical elimination. The method assumes transmission of radio signals and reception of them with measurement of the received signal powers. Determination of a direction and a value of an orientation error of the first transceiver antenna is achieved via measurement of the powers of signals transmitted by this antenna using different radiation patterns. Determination of a direction and a value of an orientation error of the second transceiver antenna is achieved via measurement of the powers of signals received by this antenna using different radiation patterns.

A film comprising a first plurality of voids is provided, wherein respective ones of the first plurality of voids have a regular n-gon geometry, and the first plurality of voids are arranged on a regular n-gon lattice having a first size. The film may comprise a second plurality of voids arranged on a regular n-gon lattice having a second size different from the first size. An optical element and manufacturing method are also provided.

The embodiments herein relate to radio sheet system at high frequencies. In an embodiment, there proposes a lens antenna system, comprising: a lens; a plurality of antenna sets attached to the lens; and a multiplexer connected to the plurality of antenna sets, for selectively activating an antenna set of the plurality of antenna sets, in order that a collimated beam is emitted through the lens from the activated antenna set. With embodiments herein, only one antenna is used to transmit a beamformed beam by lens with collimation capability, thus the embodiments may provide an alternative and more efficient way to replace beamforming functionality.

A multi-beam communication system uses an array of antenna assemblies, and RF elements, to provide two or more sets of multiple beams, where each individual set of beams can be considered a beam state. An antenna assembly has a first set of RF elements oriented to produce a first beam state, and a second set of RF elements oriented to produce a second beam state. Each set of RF elements comprise a set of output sectors, where a controller is configured to selectively activate a beam state.

In accordance with one or more embodiments, an antenna system includes a dielectric antenna having a feed point, wherein the dielectric antenna is a single antenna. At least one cable having a plurality of conductorless dielectric cores is coupled to the feed point of the dielectric antenna, wherein electromagnetic waves that are guided by differing ones of the plurality of conductorless dielectric cores to the dielectric antenna result in differing ones of a plurality of antenna beam patterns.

Methods, apparatuses, and systems for two-way satellite communication and an asymmetric-aperture antenna for two-way satellite communication are disclosed. In one embodiment, a beam pattern for an asymmetric-aperture antenna is offset in a narrow beamwidth direction, and the offset beam pattern is directed by a mechanical gimbal, with the beam pattern offset made to reduce interference with an adjacent satellite. In additional embodiments, operational areas near the equator are identified for a given offset beam pattern, or a beam pattern offset may be adjusted over time to compensate for movement of the asymmetric-aperture antenna when attached to an airplane, boat, or other mobile vehicle.
