Abstract

An electronic device includes an antenna structure. The electronic device includes a bezel and a dielectric layer. The bezel has a first position and a second position, and a bezel between the first position and the second position is configured as an antenna radiator. A first dielectric is disposed on at least a part of an inner surface of the bezel besides the bezel between the first position and the second position. A second dielectric is disposed on at least a part of a surface of the antenna radiator. The first dielectric is different from the second dielectric.

First claim
