Abstract
The present disclosure provides an antenna device. The antenna device includes a metal housing having accommodating space and a LDS antenna accommodated in the metal hosing, the metal housing includes a metal shell, a metal cover and a metal ring which cooperate and are spaced with each other, inner wall surfaces of the metal shell, the metal cover and the metal ring are respectively provided with an adhesive coated layer, the LDS antenna is laser etched on a surface of the adhesive coated layer and is coupled with the metal cover. The antenna device of the present disclosure avoids frequency offset caused by gap size difference due to assembling errors between coupled antennas, so that the coupled antennas show better performance and consistency.
