Embodiment Construction

[0012] Such as figure 1 Shown is a schematic diagram of the antenna 1 in an embodiment of the present invention. The antenna 1 includes a metal shell 10 , an antenna grounding point 30 , a coupling type antenna feeding point 40 , and a coupling type antenna grounding point 20 . The metal casing 10 is a casing of an electronic device (not shown). Please also see figure 2 , the coupling type antenna feeding point 40 is connected to the circuit board 60 of the electronic device through a first capacitor 70 and a metal 50 . The first capacitor 70 is composed of a first metal sheet 71 and the metal casing 10 sandwiching an insulator. Please also see image 3 The ground point 20 of the coupled antenna is connected to the circuit board 60 of the electronic device through a second capacitor 80 and a metal 50, the second capacitor 80 is formed by an insulator sandwiched between a second metal sheet 81 and the metal casing 10 constitute. In this embodiment, the insulator is insul...

Abstract

The invention provides an antenna which comprises a coupling antenna load point, an antenna grounding point, a metal casing and a coupling antenna grounding point. The metal casing is a casing of an electrical apparatus. The antenna grounding point is connected to a circuit board of the electrical apparatus through a metal. The coupling antenna load point is connected to the circuit board of the electrical apparatus through a first capacitor and a metal. The first capacitor is formed through clamping an insulator with a metal sheet and the metal casing. Through adjusting a distance between the coupling antenna load point and the antenna grounding point, antenna coupling adjustment is carried out. Through adjusting a distance between the coupling antenna load point and the coupling antenna grounding point, adjustment of antenna resonance frequency is carried out. By using the antenna, space of the electrical apparatus occupied by the antenna can be reduced, and a disadvantage that at present a plurality of products need to be thinned and product casings are metalized so as to make solid of a mechanism, but an antenna characteristic is sacrificed can be effectively solved.

Description

technical field [0001] The present invention relates to an antenna, in particular to an antenna arranged on the casing of an electronic device. Background technique [0002] At present, general electronic products are equipped with an independent antenna. The antenna is generally installed in the electronic device and occupies a certain space of the electronic device. After the casing is metallized, the characteristics of the antenna are affected. Contents of the invention [0003] In view of this, it is necessary to provide an antenna disposed on the housing of the electronic device. [0004] The antenna includes a metal shell, which is the shell of an electronic device; a coupling type antenna ground point is connected to the circuit board of the electronic device through a first capacitor and a first metal, and the first capacitor is formed by a first capacitor. An insulator is sandwiched between a metal sheet and the metal casing; a coupling type antenna feed point i...
