Abstract

The invention discloses a dual-band antenna and a manufacturing method thereof. The dual-band antenna comprises an insulating-medium hexahedron, a first metallic patch and a second metallic patch, wherein the first metallic patch is F-shaped and comprises an upper short side band, a lower short side band and a long side band, wherein an F shape is formed in a manner that the upper short side band, the lower short side band and the long side band respectively correspond to an upper transverse side, a lower transverse side and a vertical side of the F shape; the first metallic patch is located on the lower surface of the insulating-medium hexahedron; the second metallic patch is a metallic band and is located on the upper surface of the insulating-medium hexahedron; and the upper short side band and the lower short side band of the first metallic patch are electrically connected with the second metallic patch respectively. According to the dual-band antenna and the manufacturing method of the dual-band antenna, the problem of higher manufacturing cost due to the fact that the insulating-medium hexahedron is required for adopting an insulating material with a high dielectric constant value can be solved.

Description

technical field [0001] The invention relates to the field of communications, in particular to a dual-band antenna and a manufacturing method thereof. Background technique [0002] Currently, communication devices often require dual-band antennas. For example, in the WiFi standard of the wireless local area network, the working frequency band is divided into two frequency bands: 2.4-2.48G and 4.9G-5.8G. Therefore, a dual-band antenna needs to be used in the terminal of the wireless local area network. [0003] In the prior art, a technical solution for realizing a dual-band antenna is to lay a metal sheet, such as a copper sheet, on the surface of an insulating medium hexahedron. The shapes of the metal sheets laid in the dual-band antenna are different, which will make the effect of the antenna to send and receive signals different. Due to the limitation of the arrangement of the dual-band antenna in the prior art, an insulating material with a high dielectric constant va...
