Abstract
The invention relates to a coupled antenna which is installed on a metal outer shell. The coupled antenna comprises an excitation source, a radiation source, a coaxial transmission line and a non-conductive substrate. The excitation source and the radiation source are arranged on the surface of the non-conductive substrate. The coaxial transmission line comprises a central conductor and an outer conductor, wherein the central conductor is welded to the radiation source, and the outer conductor is welded to the excitation source. The excitation source is electrically connected with the metal outer shell to enable the metal outer shell to serve as a part of the excitation source. The metal outer shell and the excitation source serve as a whole, the whole and the radiation source are excited by each other to then achieve the radiation aim, and the coupled antenna can not be influenced by metal and has the optimal efficiency and the optimal performance.
Description
Technical field
The present invention relates to a kind of coupled antenna, relate in particular to a kind of coupled antenna being installed on metal shell.
Background technology
Current many products are for outward appearance demand, normal choice for use metal shell structure is to reach frivolous object, phase can increase consumer's purchase intention, but this kind of metal environment is not suitable for aerial radiation and design, taking notebook computer as example, designing antenna under all-metal environment, common design need increase antenna height conventionally, by antenna arrangement on non-conductive substrate surface, non-conductive substrate is fixed on metal shell, make antenna away from metallic region, to solve the problem in the radiationless space of antenna, but the standing-wave ratio of this type of antenna (VSWR), the performance such as reflection loss (Return Loss) and radiation efficiency (Antenna Radiation Efficiency) is poor, be difficult to meet user demand.
So, be necessary above-mentioned technical problem to improve.
Summary of the invention
The object of the present invention is to provide a kind of coupled antenna that not disturbed by metal.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of coupled antenna, be installed on metal shell, it comprises excitaton source, radiation source, coaxial transmission line and non-conductive substrate, described excitaton source and radiation source are arranged in non-conductive substrate surface, described coaxial transmission line has center conductor and external conductor, described center conductor is welded on radiation source, described external conductor is welded on excitaton source, described excitaton source and metal shell are electrically connected so that metal shell becomes a part for excitaton source, common and the radiation source of metal shell and excitaton source excites mutually and then reaches the object of radiation.
The excitaton source of coupled antenna of the present invention and metal shell are electrically connected so that metal shell becomes a part for excitaton source, common and the radiation source of metal shell and excitaton source excites mutually and then reaches the object of radiation, coupled antenna is not disturbed by metal comparatively, there is efficiency and the performance of better optimization, usage space also greatly reduces and incorporates in the outward appearance of metal shell, and the size of coupled antenna can also arrange comparatively less.No matter metal shell size why, can directly regulate radiation source to adjust impedance matching, makes to give off mutually energy.
Brief description of the drawings
Fig. 1 is the schematic diagram of coupled antenna of the present invention.
Embodiment
Refer to shown in Fig. 1, coupled antenna of the present invention comprises excitaton source 10, radiation source 20, coaxial transmission line 30, conductive fabric 40 and non-conductive substrate 50.
Non-conductive substrate 50 is that plastic cement, glass or ceramic material are made, it is installed in an open slotted eye 61 of metal shell 60, this slotted eye 61 is " ㄈ " shape, it has openings at one side and the outside perforation of metal shell 60, reduce the interference of metal shell 60 to coupled antenna of the present invention, promote the usefulness of coupled antenna.In other embodiments, this slotted eye 61 replaces with the fixing hole of periphery seal, and fixing hole is polygon or circle etc.Excitaton source 10 is arranged in non-conductive substrate 50 surfaces with radiation source 20, and coaxial transmission line 30 has center conductor 31 and external conductor 32, and center conductor 31 is welded on radiation source 20, and external conductor 31 is welded on excitaton source 10.
Conductive fabric 40 connects excitaton source 10 and metal shell 60, make excitaton source 10 and metal shell 60 form grounded circuit, metal shell 60 becomes a part for excitaton source 10, when coupled antenna work of the present invention, common and the radiation source 20 of metal shell 60 and excitaton source 10 excites mutually and then reaches the object of radiation, this coupled antenna is not disturbed by metal comparatively, there is efficiency and the performance of better optimization, usage space also greatly reduces and incorporates in the outward appearance of metal shell 60, and the size of coupled antenna can also arrange comparatively less.
The mode of excitation of coupled antenna energy of the present invention, no matter metal shell 60 sizes why, can directly regulate radiation source 20 to adjust impedance matching, makes to give off mutually energy.
In sum, different from traditional antenna design, the present invention can coordinate environment metal variable, makes metal shell 60 itself become a part for antenna, and can have identical electrical statutory standard, and its method for designing and step are presented below:
(1). the excited radiation source 20 that the present invention designs using coupled antenna as multiband.
(2). on metal shell 60, find a suitable position that excites, as louvre, LED lamp or other non-metallic material regions structurally, in this region, design radiation excitation source 20, see through coupling mechanism and make excitaton source 20 and the mutual exciting radiation energy of metal shell 60.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
