Document Type and Number:
WIPO Patent Application WO/2023/273600
Kind Code:
A1
Abstract:
The present application provides a lens, a lens array, and an array antenna. The array antenna comprises: a radiator array comprising a plurality of radiator units arranged according to a first array rule, and having at least a first array direction; and the lens array comprising a plurality of lens units arranged according to the first array rule, the plurality of lens units covering the plurality of radiator units in one-to-one correspondence, and each lens unit being used for adjusting the phase of an electromagnetic wave emitted by the radiator unit corresponding to the lens unit. The lens units are configured, at least along the first array direction, such that each part of the lens units has a different phase adjustment amount for the electromagnetic wave, and the lens units can adjust the electromagnetic wave into a plane wave in a first plane. In the present application, when the gain and directivity of the array antenna are ensured, there may be a large spacing between the radiator units, such that the structure of a feed network can be simplified.
