It is ceramic antennas that traditional gps antenna has many, and since the needs of industrial design how gps antenna and radio frequency amplifier are incorporated on the printed circuit board (PCB).The TaiWan, China patent announcement has disclosed a kind of GPS combined type antenna sets for No. 559348, this antenna sets comprises that GPS pottery block antenna, that a printed circuit board (PCB) (PCB), is arranged at printed circuit board (PCB) one side is arranged at the low noise amplifier (LNA, Low Noise Amplifier) of printed circuit board (PCB) opposite side.This gps antenna makes the both sides that ceramic antenna and LNA are arranged at PCB respectively the height of entire antenna group is the thickness sum of ceramic antenna, LNA and PCB, thereby makes antenna sets have bigger height.Therefore be necessary to provide a kind of antenna module can make the back shared spatial altitude of fitting together of antenna, PCB and LNA less.
[summary of the invention]
The object of the present invention is to provide a kind of antenna module of scaled-down version.
To achieve these goals, the present invention adopts following technical scheme: a kind of antenna module comprise have large stretch of electric conductor have an accepting groove with printed circuit board (PCB), lower surface as the grounding parts of antenna module and be fixed in the printed circuit board (PCB) upper surface strutting piece, be fixed in antenna body, low noise amplification module and feeder line on the strutting piece; Wherein, antenna body comprise Department of Radiation, electrically connect and form first brace of a feedback point with Department of Radiation and electrically connect with Department of Radiation and with first brace be spaced a distance with printed circuit board (PCB) on second brace that electrically connects of grounding parts; The low noise amplification module is arranged in the upper surface of printed circuit board (PCB) and is contained in the accepting groove of strutting piece, itself and described grounded part from, electrically connect with first brace of described antenna body; Thereby feeder line comprises that a heart yearn is connected with the low noise amplification module to be electrically connected with first brace and a braid is connected with grounding parts on the described printed circuit board (PCB).
Compared to prior art, antenna module of the present invention has the following advantages: the low noise amplification module is contained in the accepting groove of strutting piece, has dwindled the whole height of antenna module under the situation of the radiance that does not influence antenna body.

[embodiment]
Referring to figs. 1 through shown in Figure 3, it is the stereogram of preferred embodiment of the present invention.Among this embodiment antenna module 1 comprise strutting piece 10, be attached at antenna body 20 on the strutting piece 10, the printed circuit board (PCB) 30 and the feeder line 40 of fixed antenna body 20 and strutting piece 10.
Strutting piece 10 is a cube, and it comprises a pair of projection 11, the lower surface that extend upward from upper surface cave inward an accepting groove 12 that forms and a pair of reference column 13 that extends and be positioned at accepting groove 12 both sides from lower surface downwards.
Printed circuit board (PCB) 30 comprises that a low noise amplification module (not shown) is positioned at the zone 31 that dotted line touches off, be positioned at 31 both sides, low noise amplification module region and with the reference column 13 corresponding a pair of location holes 32 of strutting piece 10, and with first of antenna body 20, second brace 23,24,25 corresponding opening 33,34,35 usefulness are for first, second brace 23,24, thereby 25 pass and make more firm being welded on the printed circuit board (PCB) 30 and connecting with the circuit on the printed circuit board (PCB) 30 of brace 23-25.Large stretch of electric conductor (not shown) on opening 34,35 and the printed circuit board (PCB) 30 electrically connects, and opening 33 electrically connects with low noise amplifier circuit and is separated with large stretch of electric conductor.Wherein first brace 23 electrically connects and the feedback point (not shown) of formation antenna body 20 with the low noise amplification module, and second brace 24,25 links to each other with large stretch of electric conductor on the printed circuit board (PCB) 30.Large stretch of electric conductor on the printed circuit board (PCB) 30 is as the grounding parts of antenna body 20, and is separated between the low noise amplification module.
The reference column 13 of strutting piece 10 passes location hole 32 and strutting piece 10 and printed circuit board (PCB) 30 is fixed together, and wherein the electronic component in the low noise amplification module all has certain height, and it all is housed in the accepting groove 12 of strutting piece 10.Low noise amplification module, strutting piece 10 and antenna body 20 all are positioned at the upper surface of printed circuit board (PCB) 30.
In the present embodiment, strutting piece 10 is the material that a working of plastics rather than ceramic chip etc. have specific dielectric coefficient, and the structure of the accepting groove 12 of the portion that sets within it can not change the radiation characteristic of antenna body 20.And strutting piece 10 is offered accepting groove 12 in order to accommodate low noise amplification module institute load electronic component, can effectively save the space, with antenna is compared with the structure that the low noise amplification module is arranged on the printed circuit board (PCB) both sides, the whole height of antenna module of the present invention is effectively reduced.
In the present embodiment, antenna body 20 is a gps antenna.Among other embodiment, be used for the antenna of other frequency band if also can adopt this kind structure of present embodiment need be incorporated into antenna body and low noise amplification module on the same printed circuit board (PCB) time, the low noise amplification module is contained in the accepting groove of strutting piece, but the change that is noted that its shape of strutting piece of unlike material may exert an influence to antenna performance, therefore will select suitable material in order to mate corresponding antenna as required.Among other embodiment, the assembling mode of antenna body and strutting piece also can adopt various modes such as stickup, hot melt, riveted joint as required.
