Title:

LENS, LENS ANTENNA, RADIO REMOTE UNIT, AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2019/153116

Kind Code:

A1

Abstract:

The present application provides a lens, a lens antenna, a radio remote unit (RRU), and a base station. The lens comprises a substrate layer and a metal layer. At least one surface of the substrate layer is a concave surface or a convex surface, and comprises the metal layer. The metal layer comprises a metal part and a hollow part. The metal part or the hollow part is represented in a pattern array. The pattern array comprises multiple first rings. The first ring comprises multiple pattern units. The ring having a large size in the multiple first rings encloses that having a small size. At least one of the size and the rotation angle of the multiple pattern units comprised by two adjacent first rings, and two adjacent first intervals is different. The first interval is an interval between the two adjacent first rings. The technical solution provided by the present application can utilize a metal layer to make a transmitted electromagnetic wave generate the amount of phase shift so as to become less dependent on changing the thickness of a substrate layer to generate the amount of phase shift and thin the substrate layer, and thus thinning a lens.
