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.
Claims7
An antenna structure, comprising:
- a slot antenna;
- and
- at least one antenna radome having at least one dielectric layer comprising an upper surface formed with a plurality of separately single S shaped metal patterns and a lower surface formed with a plurality of separately single inverse S-shaped metal patterns corresponding to the separately single S-shaped metal patterns,
- wherein the separately single S-shaped metal patterns are respectively coupled to the corresponding separately single inverse S-shaped metal patterns to converge radiating beams outputted from the radiating element slot antenna,
- wherein the separately single S-shaped metal patterns and separately single inverse S-shaped metal patterns are oriented at a substantially zero degree angle in horizontal directions.
