In some embodiments, the antenna architecture also includes a plurality of digital back ends (DBEs) coupled to the plurality of metasurface antenna tiles, where each DBE is operable to: adjust time delays of one or more of received signals arriving from metasurface antenna tiles of the one sub-array of metasurface antenna tiles as part of time delay beamforming and combine the received signals in a digital domain to produce one or more beamformed signals, and delay transmit signals fed to the plurality of tiles in the digital domain by adjusting time delays of one or more of the transmit signals as part of time delay beamforming.

Examples disclosed herein describe an antenna architecture (e.g., a planar electronically steered antenna architecture) that enables operation at low elevation angles, down to zero degrees from the satellite. The proposed ‘3SA’ architecture may improve power consumption and array footprints. The proposed ‘3SA’ architecture can support aero terminal implementation on aircraft, enabling the use of GEO, MEO and LEO satellites even in regions having low elevation angles. The architecture may include a horizontal antenna array and vertical antenna array as well as a controller for switching between the antenna arrays.

A low sidelobe beam forming method and dual-beam antenna schematic are disclosed, which may preferably be used for 3-sector and 6-sector cellular communication system. Complete antenna combines 2-, 3- or -4 columns dual-beam sub-arrays (modules) with improved beam-forming network (BFN). The modules may be used as part of an array, or as an independent 2-beam antenna. By integrating different types of modules to form a complete array, the present invention provides an improved dual-beam antenna with improved azimuth sidelobe suppression in a wide frequency band of operation, with improved coverage of a desired cellular sector and with less interference being created with other cells. Advantageously, a better cell efficiency is realized with up to 95% of the radiated power being directed in a desired cellular sector.

The second antenna module is provided in a coupling area, in which the second roof rail is coupled to the roof panel, and the second antenna module is inserted into the second roof rail. The plurality of antennas are disposed in the first and second antenna modules in a distributed manner.

A communications device comprises controller circuitry configured in combination transmitter and receiver circuitry to form one or more beams to transmit data, each of the beams having a different angular bias with respect to a location of the communications device, to transmit the signals, using a first of the beams, to change, dependent on one or more sets of predetermined conditions being met, a beam width of the first of the beams, and to re-transmit the signals using the first of the beams having the changed beam width.

One end of a second feeding line is connected to a first feeding line configured to transmit a first polarization at a first position and the other end is connected to a patch at a second position. One end of a third feeding line is connected to the first feeding line and the other end is connected to the patch at a third position. One end of a fourth feeding line is connected to the patch at a fourth position and configured to transmit a second polarization, wavelengths of the first and second polarizations being the same as each other. The second and third feeding lines are configured to cause the first polarization at the second position to be in opposite phase to the first polarization at the third position. A distance between the second and fourth positions is equal to a distance between the third and fourth positions.

A variably controlled stagger antenna array architecture is disclosed. The array employs a plurality of driven radiating elements that are spatially arranged having each radiating element or element groups orthogonally movable relative to a main vertical axis. This provides a controlled variation of the antenna array's azimuth radiation pattern without excessive side lobe radiation over full range of settings.

Various embodiments of a communication system operative to form, direct, and narrow communication beams using an array of electromagnetic radiators and a beam-narrowing architecture. A beam-width of an electromagnetic beam is narrowed, thereby increasing the concentration of electromagnetic energy in the beam and achieving a significant antenna gain. In various embodiments, the direction of an electromagnetic beam may be altered to improve communication between a transmitter and a receiver. In various embodiments, the system is a millimeter-wave system with a millimeter-wave array and millimeter-wave beams.

Incoming calls are received from audio capable devices. A call processing server receives an incoming call from an audio-capable device to a destination number, and detects availability for an ancillary source device linked to the audio-capable device. A set of data is provided to the ancillary source device. The set of data specifies graphical menu options for functions supported by the call processing server. The ancillary source device provides an indication of a selection of one of the graphical menu options. In response to the indication, a call transfer for the incoming call is implemented.

A device for transmitting and/or receiving electromagnetic signals includes an antenna array, a combiner/splitter unit, a signal processing unit, and a switch.
