Description
Technical field
The utility model relates to the communications field, relates in particular to a kind of paster antenna.
Background technology
Antenna is an energy conversion device in the GSM.In mobile communication, directional antenna uses half-wave doublet to form antenna, and generally speaking, the wave beam of half-wave doublet is 78 degree, can beamwidth be constrained in about 65 degree through reflecting plate, but this moment, antenna volume is bigger, is not easy to transport and install.
Used paster antenna to replace the half-wave doublet, to address the above problem at present.The characteristics of paster antenna are made up of one or several radiation fins, can carry out 2 feeds, also can four-point feed.At present, the feeding classification of industry paster antenna mainly contains two kinds, and a kind of is the coupling of falling L feed, and another kind is PIN probe and following radiation fin welding carrying out feed.
But the coupling of falling L feeding technique scheme, the distance between distributing point and the radiation fin is bigger to the electric parameter influence of standing wave etc., and paster is fixed with the medium post, thereby relatively poor apart from consistency between distributing point and the radiation fin, causes the consistency of complete machine relatively poor.The PIN probe carries out the feed scheme then because of radiation fin need weld with feed with following radiation fin welding, difficult operation when design and production assembling.
The utility model content
The embodiment of the utility model provides a kind of paster antenna, has guaranteed the consistency of producing, and has reduced operation easier.
For achieving the above object, the embodiment of the utility model adopts following technical scheme:
A kind of paster antenna is provided, comprises:
The upper strata paster;
With the integrated feed probes of said lower floor paster.
Said feed probes for form through impact style with the integrated feed probes of said lower floor paster.
The number of said feed probes is two.
The number of said feed probes is four.
The place straight line of the polarised direction of said feed probes is vertical each other.
The shape of said upper strata paster is identical with said lower floor patch shape, and the area of said upper strata paster is less than or equal to the area of said lower floor paster.
The shape of said upper strata paster, said lower floor paster comprises: square, circle, regular hexagon, octagon.
Said upper strata paster is parallel with the lower floor paster.
Said feed probes is vertical with the lower floor paster.
The paster antenna that the utility model embodiment provides on lower floor's paster, includes and the integrated feed probes of lower floor's paster.There is not the distance between distributing point and the lower floor's paster in the relatively existing coupling of falling L feeding technique, thereby can guarantee the consistency of producing; Existing P IN probe welding feeding technique need not during assembling to carry out welding operation relatively, the difficulty when having reduced design and assembling.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 2, wherein Fig. 2 (a) is the vertical view of lower floor's paster 12, and Fig. 2 (b) is the end view of lower floor's paster 12.At present embodiment, feed probes 13 is on lower floor's paster 12, utilizes mould to pass through that impact style forms, and this feed probes 13 is connected stereogram as shown in Figure 3 with lower floor paster 12 after the punching press.
Need to prove; It is identical with its mold shape to utilize mould to pass through the shape of the feed probes 13 that impact style forms; Can be the identical probe 13 of shape that utilizes identical mould to form, also can be the variform probe 13 that utilizes different dies to form, and can be vertical through the probe 13 that forms after the punching press and lower floor paster 12; Also can out of plumb, the utility model does not limit this.
In the present embodiment, the number of exemplary hypothesis feed probes 13 is four, and promptly paster antenna 10 is a four-point feed.But present embodiment is not limited to this, the number of feed probes be as shown in Figure 6 two also passable, this moment, paster antenna was 2 feeds.But no matter the number of feed probes is several, because two-way probe place straight line is orthogonal, carries out direct feed along the diagonal of radiating element respectively in the present embodiment, has therefore formed ± 45 ° of dual-polarized radiation.
In the paster antenna 10 that present embodiment provides, upper strata paster 11 is square with lower floor's paster 12, and the area of upper strata paster 11 can be less than the area of lower floor's paster 12, and is as shown in Figure 1; The area of upper strata paster 11 also can equal the area of lower floor's paster 12, and is as shown in Figure 4.
In addition; In the paster antenna 10 that present embodiment provides, upper strata paster 11 is square with lower floor's paster 12, and present embodiment is not limited to this; Upper strata paster 11 can also be other shapes with lower floor's paster 12, such as regular hexagon, octagon or circle as shown in Figure 5 etc.
Have, can like this, can alleviate the weight of antenna with adopting the 1mm aluminium sheet be made as lower floor's paster of radiation fin, can adopt other thickness yet, the utility model does not limit this.For weight and the antenna cost that further alleviates antenna, can adopt the aluminium sheet of 0.5mm to make as the upper strata paster of parasitic element, also can adopt other thickness to make, the utility model does not limit this yet.In addition, parallel as the upper strata paster of parasitic element with lower floor's paster as radiation fin.
Need to prove; In the paster antenna 10 that the utility model provides; 12 uses of upper strata paster 11 and lower floor's paster strutting piece is connected; Wherein, strutting piece can select for use plastic cement or plastics to carry out being connected of upper strata paster 11 and 12 of lower floor pasters, also can be that other materials the utility model does not limit this.
The paster antenna that the utility model embodiment provides on lower floor's paster, is formed with and the integrated feed probes of lower floor's paster through impact style.There is not the distance between distributing point and the lower floor's paster in the relatively existing coupling of falling L feeding technique, thereby can guarantee the consistency of producing; Existing P IN probe welding feeding technique need not during assembling to carry out welding operation relatively, the difficulty when having reduced design and assembling.
The above; Be merely the embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range of said claim.
