METHOD AND TRANSMITTER FOR ANALOG BEAM STEERING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17915910 titled 'METHOD AND TRANSMITTER FOR ANALOG BEAM STEERING

Simplified Explanation

The abstract describes a transmitter designed for analog beam steering, which involves adjusting the direction of radio signals using multiple antennas. Here are the key points:

  • The transmitter has multiple antenna branches, each with an antenna.
  • A signal splitter is used in each antenna branch to divide the analog radio signal into several beam signals.
  • The number of beam signals corresponds to the desired number of beams to be transmitted.
  • Each beam signal is then phase shifted using a phase shifter, based on a specific phase shift setting for that beam and antenna branch.
  • The phase shift settings are obtained from a single look-up table.
  • The phase-shifted beam signals are combined into a single combined signal using a signal combiner.
  • The transmitter sends the combined signal from the antenna of that antenna branch to a receiver.

Potential applications of this technology:

  • Wireless communication systems that require precise control over the direction of radio signals.
  • Radar systems that need to steer beams for target detection and tracking.
  • Satellite communication systems that can benefit from beamforming to improve signal strength and reduce interference.

Problems solved by this technology:

  • Analog beam steering allows for more flexibility and accuracy in directing radio signals compared to traditional fixed antennas.
  • The use of a single look-up table simplifies the phase shift settings and reduces complexity in the transmitter design.
  • The combination of multiple phase-shifted beam signals enhances the overall signal strength and quality.

Benefits of this technology:

  • Improved signal coverage and range by steering beams towards specific locations or receivers.
  • Reduced interference and improved signal quality by focusing beams in desired directions.
  • Simplified design and implementation of the transmitter through the use of a single look-up table for phase shift settings.


Original Abstract Submitted

Disclosed is a transmitter configured for analog beam steering, the transmitter comprising a plurality of antenna branches, each having an antenna (). The transmitter comprises, at each of the antenna branches, a signal splitter () for splitting an analog radio signal into a number of beam signals, the number of beam signals equals a number of desired beams to be transmitted. Further, the transmitter comprises, for each of the number of beam signals, a phase shifter () for phase shifting the beam signal according to a phase shift setting for that beam and for that antenna branch, the phase shift settings being taken from a single look-up table, and a signal combiner () for combining the phase shifted beam signals into one combined signal. Further, the transmitter is arranged for transmitting the combined signal from the antenna () of that antenna branch towards a receiver.
