Abstract

The invention discloses an antenna apparatus. The antenna apparatus comprises a metal casing, a first feeding point, a point of grounding and a first match circuit, wherein a first slit and at least one first micro slit belt are formed in the metal casing; a first micro slit belt is communicated with a first micro slit and the side edge of the metal casing to form a first insulating segment so as to enable the first insulating segment to separate a first radiation part and a second radiation part; the first feeding point, and the point of grounding are arranged on the second radiation part; the first feeding point is electrically connected with the first radiation part through the first match circuit; and the first radiation part is electrically connected with the point of grounding. The invention also discloses a metal casing and a mobile terminal. The radiator of the antenna apparatus is a metal casing of a mobile terminal so that the radiation efficiency of the antenna apparatus is improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a metal casing, an antenna device and a mobile terminal using the antenna device. Background technique [0002] With the development of science and technology and the higher and higher signal requirements of users for electronic products, many mobile terminals with antennas such as mobile phones on the market currently use metal shells to ensure the strength of use while satisfying the texture and improving the user experience. feel. As we all know, metal is a signal shielding material. In order to avoid the signal shielding of the metal casing from affecting the antenna efficiency, the casing is usually designed to combine metal and non-metal, so that the antenna structure is located in the non-metal area. The non-metal area is usually set at both ends of the mobile terminal. Located outside the shielded display area, a circuit board is installed inside the non-metal a...
