Abstract

Systems and techniques are provided for radio frequency (RF) beamforming using a plurality of differently skewed cylindrical lenses. In one example, an apparatus for wireless communication may include a plurality of cylindrical lenses, each respective cylindrical lens of the plurality of cylindrical lenses having a respective first surface and a respective second surface opposite to the respective first surface. Each respective cylindrical lens can include a power direction corresponding to a curvature of each respective first surface and a non-power direction that is orthogonal to the power direction. The apparatus can further include at least one linear antenna array disposed proximate to each respective second surface of each respective cylindrical lens, the at least one linear antenna array including a plurality of antenna array elements.

Dependent claims

A wireless communication apparatus, comprising:

a plurality of cylindrical lenses, each respective cylindrical lens of the plurality of cylindrical lenses having a respective first surface and a respective second surface opposite to the respective first surface, wherein each respective cylindrical lens includes a power direction corresponding to a curvature of each respective first surface and a non-power direction that is orthogonal to the power direction;
and
a plurality of linear antenna arrays arranged in a parallel configuration along the power direction, wherein each linear antenna array of the plurality of linear antenna arrays is coplanar and disposed proximate to the respective second surface of a corresponding cylindrical lens of the plurality of cylindrical lenses and including a respective plurality of antenna array elements aligned in the non-power direction along a central axis of the corresponding cylindrical lens, wherein each linear antenna array is associated with a corresponding beam angle based on an offset between the central axis and an optical axis of the corresponding cylindrical lens.

Dependencies are inferred from the claim text.
