Three-dimensional antenna module and electronic device

Abstract

A three-dimensional antenna module includes a main antenna radiator and a ground radiator. The main antenna radiator includes a first segment, a second segment, a third segment, and a fourth segment. The first segment includes a feed end. The second and third segments extend from the first segment away from the feed end in opposite directions. The fourth segment extends from the first segment and is located next to the third segment. The ground radiator is located next to the main antenna radiator and is in a different plane from the main antenna radiator. The projection of the main antenna radiator onto the plane containing the ground radiator partially overlaps with the ground radiator, and the projection of the feed end onto the plane containing the ground radiator also overlaps with the ground radiator. The three-dimensional antenna module resonates to generate a low-frequency band, a first high-frequency band, a second high-frequency band, and a third high-frequency band.
