Abstract
The invention relates to a slot antenna which is installed on a metal housing of a mobile device. The slot antenna comprises a first slot penetrating the metal housing, a flexible substrate, a metal layer, a conductive adhesive layer, and a coaxial cable. Located between the flexible substrate and the conductive adhesive layer, the metal layer is electrically connected to the metal housing. A feed point and a short-circuit point are installed in proper positions of the metal layer on bilateral sides of a second slot. The portions of the flexible substrate with respect to the feed point and the short-circuit point are removed. The feed point and the short-circuit point are welded with the coaxial cable together. The slot antenna further comprises the second slot which penetrates the flexible substrate and the metal layer and is aligned to the first slot. The first slot and the second slot are stacked and are communicated with one another, thereby concurrently constituting the slots used as transmission apertures of the slot antenna. The slot antenna is easy to debug, simple, and low cost.
Description
Technical field
The present invention relates to a kind of slot antenna, particularly relate to a kind of slotted eye that utilizes as the slot antenna of radiating aperture.
Background technology
Multiband concealed antenna (Multi Band-Internal Antenna), under all-metal organizational environment, there will be the problem that signal energy cannot transmit.After unremitting effort, people have invented slot antenna, metal shell arranges a slotted eye, feedback point and short dot are set in the appropriate location of slotted eye both sides, weld together with a coaxial line, utilize slotted eye as the radiating aperture of antenna, under metal environment can be solved,, there is debugging more difficult in the problem that antenna energy transmits, but traditional slot antenna, during debugging, be difficult to the size of adjustment fluting, often relate to the problem that metal shell needs die sinking again, cause R & D Cost greatly to increase.
So, be necessary that a kind of new slot antenna of design is to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide a kind of slot antenna being convenient to debug.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of slot antenna, in order to be arranged on the metal shell of mobile device, it comprises the first slotted eye run through on metal shell, flexible parent metal, metal level, conductive adhesive layer and coaxial line, described metal level is between flexible parent metal and conductive adhesive layer and electrically conduct with metal shell, described metal level is provided with feedback point and a short dot in the appropriate position of the second slotted eye both sides, described flexible parent metal correspondence feedback point is removed with the position of short dot, described feedback point and short dot and coaxial line weld together, described slot antenna also comprises and runs through flexible parent metal and metal level and the second slotted eye aligned with the first slotted eye, first, second slotted eye is stacked and mutually through, first, the slotted eye that second slotted eye forms slot antenna is jointly using as radiating aperture.
As a further improvement on the present invention, described first slotted eye is greater than the length of the second slotted eye.
As a further improvement on the present invention, described flexible parent metal is the film that insulating material is made.
As a further improvement on the present invention, described flexible parent metal is flexible flat shape after being combined with metal level.
As a further improvement on the present invention, described metal level is layers of copper.
As a further improvement on the present invention, described conductive adhesive layer is bonded in the inner surface of metal shell.
Slot antenna of the present invention also comprises and runs through flexible parent metal and metal level and the second slotted eye aligned with the first slotted eye, first, second slotted eye is stacked and mutually through, first, the slotted eye that second slotted eye forms slot antenna is jointly using as radiating aperture, during slot antenna debugging of the present invention, only need remove the flexible parent metal of a part of metal level and correspondence thereof, or the size of metal level is increased by welding, realize reducing or expanding the size of the second slotted eye and then change the slotted eye of slot antenna, thus the frequency reached required for slot antenna, debugging easily, simply, cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that slot antenna of the present invention is arranged on metal shell.
Fig. 2 is the floor map of slot antenna of the present invention.
Embodiment
Refer to shown in Fig. 1 to Fig. 2, slot antenna 10 of the present invention, in order to be arranged on the metal shell 20 of mobile device, metal shell 20 offers the first slotted eye 21 run through.Described slot antenna 10 comprises flexible parent metal 11, metal level 12, conductive adhesive layer 13 and a coaxial line 14 and runs through flexible parent metal 11, metal level 12 the second slotted eye 15 aligned with the first slotted eye 21, first, second slotted eye 15,21 is stacked and mutually through, first, second slotted eye 21,15 forms the slotted eye of slot antenna 10 jointly, as radiating aperture, the first slotted eye 21 is greater than the length of the second slotted eye 15.
The film that flexible parent metal 11 is made for insulating material, metal level 12 is layers of copper, metal level 12 is between flexible parent metal 11 and conductive adhesive layer 13, it is flexible flat shape after flexible parent metal 11 is combined with metal level 12, conductive adhesive layer 13 is bonded in metal shell 20 inner surface, and metal level 12 and metal shell 20 are electrically conducted.
Metal level 12 is provided with feedback point 121 and short dot 122 in the appropriate position of the both sides of the second slotted eye 15, flexible parent metal 11 correspondence feedback point 121 is removed with the position of short dot 122, make feedback point 121 and short dot 122 be exposed to flexible parent metal 11 outside, weld together with coaxial line 14.
When slot antenna 10 of the present invention is debugged, only need remove the flexible parent metal 11 of a part of metal level 12 and correspondence thereof, or the size of metal level 12 is increased by welding, realize reducing or expanding the size of the second slotted eye 15 and then change the slotted eye of slot antenna 10, thus the frequency reached required for slot antenna 10, debugging is easily, simple, cost is low.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
