ABSTRACT:
An antenna structure includes a radiating element and an antenna radome. The antenna radome has at least one dielectric layer, which has an upper surface having many S-shaped metal patterns and a lower surface having many inverse S-shaped metal patterns corresponding to the S-shaped metal patterns. The S-shaped metal patterns are respectively coupled to the corresponding inverse S-shaped metal patterns to converge radiating beams outputted from the radiating element.
