Increasing area of grounding section and adding protective membrane improves grounding effect, reduces depreciation, raises gain value and prolongs service life of antenna.
Description
[technical field]
The present invention relates to the improvement method of a kind of antenna ground portion performance.
[background technology]
Existing antenna all comprises Department of Radiation, grounding parts and feeder line mostly.But this type of antenna is easy to generate loss, thereby causes the reduction of antenna efficiency because the grounding parts electric conductivity is not ideal enough.In order to reduce aerial loss, just require to improve the conductance of earthed surface, for example: substitute actual ground with limited metallic plate or wire netting.
The Chinese patent of bulletin disclosed a kind of dull and stereotyped inverted F shaped antenna that improves the grounding parts area for 01221387.X number on November 13rd, 2002.The primary structure of this inverted F shaped antenna comprises that antenna body and extends grounding parts, aforementioned antenna body has load point, earth point, resoance radiation main body and grounding parts, aforementioned extension grounding parts is connected in grounding parts and forms an angle that bends with grounding parts, and provides inverted F shaped antenna preferable ground connection effect by extending grounding parts.Though above-mentioned antenna can improve the conductive effect of antenna ground portion, reduce loss, improve gain, but the range of application of above-mentioned antenna is also narrower, when antenna be applied to other equipment as: in the time of in the device of wireless local area network access point, these equipment can't provide bigger conducting surface; And the grounding parts of its extension is directly exposed in the air, and through oxidation by air easily after a while, the surface generates oxide layer, thereby can cause the service behaviour of antenna to reduce, and reduces the life-span of antenna
[summary of the invention]
The purpose of this invention is to provide and a kind ofly make antenna have ground connection effect preferably and can prevent its oxidized antenna ground portion performance improvement method in grounding parts surface.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: the first step: antenna assemblies on electronic equipment, and is utilized Department of Radiation and grounding parts and the electronic equipment internal circuit electrical couplings of feeder line with antenna.Second step: choose a ground connection auxiliary member, its maximum area is no more than the surface area of electronic equipment internal remaining space.The 3rd step: ground connection auxiliary member and described grounding parts are electrically connected.The 4th step: the surface that contacts with air at the ground connection auxiliary member adds upper protective film.
Compared with prior art, the antenna advantage that the present invention makes is: by increase the ground connection auxiliary member at grounding parts, make its have bigger contact area and more good electrical conductivity improve the operating characteristic of antenna.By the surface that contacts with air at the ground connection auxiliary member increase diaphragm in order to prevent the ground connection auxiliary member from contacting with air by its oxidation.

[embodiment]
See also shown in Figure 1ly, present embodiment is chosen the plane inverse F type printed antenna and is improved antenna ground portion performance.Above-mentioned plane inverse F type printed antenna 1 comprises planar substrates 10, is arranged on antenna body of substrate 10 upper surfaces (not label) and feeder line 14, wherein substrate 10 is made by insulating material, and antenna body comprises first Department of Radiation 11, second Department of Radiation 12, grounding parts 13 and the ground connection auxiliary member 15 that is banded, and described first Department of Radiation 11 and second Department of Radiation 12 upwards bend extension from the top edge at grounding parts 13 two ends respectively
First Department of Radiation 11 roughly is the L type, comprises the first arm 110 parallel with grounding parts 13 and first connecting portion 111 that connects the first arm 110 1 ends and grounding parts 13.Second Department of Radiation 12 roughly is the L type, comprises second arm 120 parallel with grounding parts 13 and second connecting portion 121 that connects second arm, 120 1 ends and grounding parts 13.The first arm 110 and second arm 120 are respectively along the relative horizontal parallel setting of lateral margin of first connecting portion 111 and second connecting portion 121.
Described feeder line 14 mainly comprises internal core wire 140 and shielding layer 141, and wherein internal core wire 140 is welded on the first arm 110, and shielding layer 141 is welded on the grounding parts 13.Can regulate the input impedance of antenna 1 by changing the welding position of internal core wire 140 on the first arm 110.
See also illustrated in figures 1 and 2ly, ground connection auxiliary member 15 extends and is set in parallel on the grounding parts 13 from the upper surface on grounding parts 13 right sides.Above-mentioned ground connection auxiliary member 15 can be a small pieces Copper Foil, aluminium foil or other metal materials.Ground connection auxiliary member 15 can directly be welded on the grounding parts 13, also can utilize conducting resinl that both are connected or by other modes ground connection auxiliary member 15 and grounding parts 13 is electrically connected.By on grounding parts 15, increasing ground connection auxiliary member 16, make its have bigger contact area and more good electrical conductivity improve the operating characteristic of antenna.The surface that diaphragm 16 can contact with air attached to ground connection auxiliary member 15 by existing modes such as plating, spraying or pad pastings.By increase at ground connection auxiliary member 15 diaphragms 16 in order to prevent ground connection auxiliary member 15 from contacting with air by its oxidation.Said protection film 16 can be conductive fabric, polyimide insulating tape, polyester fiber insulating tape or other insulating material.
All can improve its grounding parts performance with the microstrip antenna or the other forms of printed antenna of plane inverse F type printed antenna similar by said method.Described ground connection auxiliary member size is determined by its application, when there is bigger space the inside of the residing electronic equipment of antenna, then described ground connection auxiliary member can be designed to bigger parts, and the area of hour then described ground connection auxiliary member is also less when the electronic equipment internal space.And the present invention adopts thin metal material to make that auxiliary earth portion is bent, and then can effectively utilize the space of electronic equipment internal.
