Antenna array for point-to-point microwave radio system
First Claim
1. An antenna array for communicating information via a wireless microwave link between two locations, the antenna array comprising:
- at least two antenna elements each to transmit information as a narrow beam signal to be directed toward a receiver at a remote location, the antenna elements including at least one antenna element to transmit a narrow beam signal toward a redirection point different from the receiver; and
a redirection device located at the redirection point to receive the narrow beam signal from the at least one antenna element and to redirect the received narrow beam signal toward the receiver, wherein the redirection point is located such that the narrow beam signals from the at least two antenna elements converge and overlap to form an interference pattern proximate to the receiver, the interference pattern includes peaks and nulls having a peak-to-peak spacing narrower than a width of each of the received narrow beam signals.

Abstract
A system and method for communicating information between two locations via a wireless microwave link is provided. The system includes at least two antennas, each to transmit information as a narrow beam signal to be directed toward a focal point at a remote location. The antennas include at least one antenna to transmit a narrow beam signal toward a redirection point different from the focal point. A redirection device is located at the redirection point to receive the narrow beam signal from the at least one antenna element and to redirect the received narrow beam signal toward the receiver. The redirection point is located such that the narrow beam signals from the at least two antenna elements converge and overlap to form proximate to the receiver, an interference pattern that includes peaks and nulls having a peak-to-peak spacing narrower than the width of each received narrow beam signal.

13. A communication system for communicating information via a wireless link between a first location and a second location, comprising:
-
a first antenna array arranged at the first location including; at least two antenna elements each to transmit information as a narrow beam signal to be directed toward a second location, the antenna elements including at least one antenna element to transmit a narrow beam signal toward a redirection point different from the second location; and a redirection device located at the redirection point to reflect the narrow beam signal from the at least one antenna element and to redirect the received narrow beam signal toward the second location; wherein the narrow beam signals directed towards the second location are spaced apart by a separation distance at the first location that results in an interference pattern being formed at the second location with peak-to-peak spacing narrower than the individual antenna element beams, the interference pattern including peaks and nulls; and a second antenna array arranged at the second location including at least two antenna elements to receive the narrow beam signals from the first antenna array. - View Dependent Claims (16)

27. A method of communicating information via a wireless link between a first location and a second location, the method comprising:
-
transmitting a first narrow beam signal from the first location to be directed towards a receiver at the second location; transmitting at least a second narrow beam signal from the first location towards a first redirection point associated with the first location; redirecting the second narrow beam signal from the first redirection point towards the receiver; and spacing the first and second narrow beam signals apart by a predetermined separation distance at the first location such that the narrow beam signals from the first location converge and overlap to form an interference pattern proximate to the receiver, the interference pattern including peaks and nulls having a peak-to-peak spacing narrower that a width of each of the received narrow beam signals. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
