Abstract
A coherent near-field array. The array consists of a number of high-gain elements, each of which directs its beam at the desired target area (either mechanically or electronically). Each element is coherently fed, so that the phase relationships between different feeds are constant or slowly varying. The elements in the array may be spaced many wavelengths apart. The array relies on interference to generate a number of power density peaks within the target area.
Claims26
An antenna array comprising:
- a plurality of elements and
- means for independently steering a beam output by each of said elements to provide multiple overlapping beams that mutually interfere at a target to provide a number of isolated hot spots.
Dependencies are inferred from the claim text.
