Patent ID: 7884778

Claim:
An antenna structure, comprising: a radiating element; and an antenna radome, placed within a near-field of the radiating element, the antenna radome comprising: a plurality of S-shaped metal patterns; a plurality of inverse S-shaped metal patterns, corresponding to the S-shaped metal patterns respectively; and a plurality of dielectric layers, at least comprising a first dielectric layer and a second dielectric layer, an upper surface of the first dielectric layer being formed with part of the S-shaped metal patterns, a lower surface of the first dielectric layer being formed with the corresponding inverse S-shaped metal patterns, an upper surface of the second dielectric layer being formed with another part of the S-shaped metal patterns, a lower surface of the second dielectric layer being formed with the corresponding inverse S-shaped metal patterns; wherein the S-shaped metal patterns are respectively coupled to the corresponding inverse S-shaped metal patterns to converge radiating beams in the propagation direction of the radiating beams outputted from the radiating element.
