Abstract

The invention provides an antenna device comprising a first radio frequency transceiver circuit, a first matching circuit, a housing, and a frequency modulation element. The housing includes a first side and a conductive area with a micro-slit tape formed by a plurality of micro slits; the micro-slit tape is adjacent to the first side of the housing; and the opening of the micro-slit tape is arranged on the first side of the housing. The first radio frequency transceiver circuit is connected with the conductive area electrically by the first matching circuit. The frequency modulation element is connected between the conductive area and the ground. In addition, the invention also provides terminal equipment. According to the invention, the overall appearance effect of the terminal equipment can be guaranteed; and the adverse effect on the antenna performance by hand holding by a user can be reduced.

Description

technical field [0001] The present invention relates to mobile communication technology, and in particular, to an antenna device and terminal equipment. Background technique [0002] In the market, all-metal casings are more and more popular with consumers, so the casing of the existing terminal equipment will adopt a structure with a micro-slit strip. The feed will be electrically connected to the metal shell, so that the metal shell acts as the radiating part of the terminal device, thereby forming a shell slot antenna. Therefore, the visual effect of the all-metal shell of the terminal device can be ensured, and the metal shell can be As part of the antenna unit, the limited space of the terminal equipment is fully utilized. [0003] However, when the user holds the terminal device, the user's hand usually contacts the micro-slit tape. Since the human body can be regarded as a conductor, the radiation performance of the slot antenna of the casing will be adversely affect...
