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, in particular to an antenna device and terminal equipment. Background technique [0002] In the market, all-metal shells are becoming more and more popular with consumers, so the shells of existing terminal equipment will adopt a structure with micro-slits. The micro-slits include multiple micro-slits, and metal strips are filled between the micro-slits. The antenna device The feed source will form an electrical connection with the metal shell, so that the metal shell acts as the radiation part of the terminal device, thereby forming a shell slot antenna, so the visual effect of the all-metal shell of the terminal device can be ensured, and the metal shell As a part of the antenna device, make full use of the limited space of the terminal equipment. [0003] However, when the user holds the terminal device, the user's hand usually comes into contact with the micro-slit strip. Since the ...
