Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the embodiments and the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0031] see figure 1 , the microstrip fed slot antenna in this embodiment includes: a dielectric plate 11, a housing 12 and a microstrip line 13, wherein

[0032] The housing 12 includes at least a first part, the material of the first part is a metal material, and a slit 120 for signal radiation is engraved on the first part, that is, the housing can be all metal material and engraved with a slit, or part of the metal material (the rest can be plastic), with slots engraved on the shell of the metal part.

[0033] The dielectric board 1...

Abstract

The invention provides a microstrip-fed slot antenna and a mobile terminal. The microstrip-fed slot antenna comprises a housing, a media plate and a microstrip line. The housing at least comprises a first part, and the first part is made of a metal material and is carved with slots for signal radiation. The media plate is arranged on the first part of the housing, wherein the media plate comprises a first surface and a second surface opposite to the first surface, and the first surface is in contact with the first part of the housing. The microstrip line is arranged on the second surface of the media plate, and at least a part of the microstrip line is opposite to at least a part of the slots. The microstrip line is used for exciting slot radiation, which can eliminate an antenna window of a full metal housing for mounting the antenna, and can realize a full metal housing structure of the mobile terminal.

Description

technical field [0001] The invention relates to a slot antenna, in particular to a microstrip feeding slot antenna and a mobile terminal. Background technique [0002] A notebook with a full metal casing is the goal that many notebook manufacturers have been pursuing. At present, one of the most important reasons why a notebook with an all-metal casing cannot be realized is that the antenna used for wireless communication cannot radiate electromagnetic waves in a metal shield. [0003] In the prior art, the slot antenna usually adopts the microstrip feeding mode and is externally placed on the notebook with a plastic casing. Since this solution is to place a metal plate on the plastic casing, it is not suitable for a notebook with a full metal casing. Of course, an all-metal casing can be realized by means of an external antenna, but its convenience, durability, integrity and aesthetics are far from meeting the requirements of notebook manufacturers.
