Abstract
Various embodiments of a millimeter-wave wireless point-to-point or point-to-multipoint communication system which enables determining preferred directions of transmissions, and transmitting in such preferred directions without routing radio-frequency signals. The system comprises a millimeter-wave focusing element, multiple millimeter-wave antennas, and multiple radio-frequency-integrated circuits (“RFICs”). In various embodiments, preferred directions are determined, and millimeter-wave beams are transmitted in the preferred directions.

A method for controlling a direction of a millimeter-wave beam in a point-to-point millimeter-wave communication system, comprising:
- using a first millimeter-wave radiating source, located at a first location on a focal surface of a millimeter-wave focusing element, to transmit a millimeter-wave beam via said millimeter-wave focusing element, wherein said millimeter-wave beam having a first direction consequent upon the first location;
- determining a desired direction for the millimeter-wave beam, wherein said desired direction is expected to improve performance of a point-to-point millimeter-wave communication system employing the millimeter-wave beam;
- identifying, out of a plurality of millimeter-wave radiating sources, a second millimeter-wave radiating source located at a second location on the focal surface of the millimeter-wave focusing element, which when in use will result in a second direction for the millimeter-wave beam that is closest to the desired direction for the millimeter-wave beam;
- and
- using the second millimeter-wave radiating source to transmit the millimeter-wave beam having the second direction consequent upon the second location, thereby improving performance of the point-to-point millimeter-wave communication system.
A method for directing millimeter-wave beams, comprising:
- determining a direction via which a millimeter-wave beam is to be transmitted;
- identifying, out of a plurality of millimeter-wave antennas placed at different locations on a focal surface of a millimeter-wave focusing element, a first millimeter-wave antenna which is:
- best placed, relative to a focal point of said millimeter-wave focusing element, to best facilitate transmission of said millimeter-wave beam via said direction;
- and
- generating, by a first radio-frequency-integrated-circuit located in close proximity to said first millimeter-wave antenna, a millimeter-wave signal which is delivered to said first millimeter-wave antenna, thereby transmitting said millimeter-wave beam toward said direction.
A millimeter-wave communication system operative to direct millimeter-wave beams, comprising:
- a millimeter-wave focusing element, operative to focus millimeter-wave beams;
- a plurality of millimeter-wave antennas, placed at different locations on a focal surface of said millimeter-wave focusing element;
- and
- a plurality of radio-frequency-integrated-circuits, placed in association with said plurality of millimeter-wave antennas, such that:
- (i) each of said plurality of millimeter-wave antennas has at least one of said radio-frequency-integrated-circuits located in close proximity, and (ii) each of said plurality of millimeter-wave antennas is operative to receive a millimeter-wave signal from said at least one of said radio-frequency-integrated-circuits located in close proximity.
