The feed-in structure improvement of antenna

Technical field

The utility model relates to a kind of feed-in structure improvement of antenna, and particularly a kind of special construction of antenna feed-in structure is formed, and can impel antenna module electrically connect feed-in structure simpler and easy, and the required electric circuitry packages of electronic equipment of arranging in pairs or groups easily.

Background technology

The feed-in device of existing antenna is formed mode, as shown in Figure 1, its cylindrical surface spiral by antenna axle 10 is wound with the antenna groups 11 in several loops, this axle 10 has an axial passage 12, its inside need have a clad lining 13 to surround a feed-in device conductor 14, and then form a feed-in device structure 15 jointly, and utilize this feed-in device structure 15 and antenna groups 11 electrically connects, wherein axial passage 12 inwalls of this axle 10 manufacturing that clad lining 13 will be set and surround feed-in device conductor 14, assembling process has belonged to difficult, add clad lining 13 and be the concentric structure with feed-in device conductor 14, when the antenna 111 in a certain loop, axle 10 tops should be with clad lining 13 electrically connects, if assembling procedure is careless slightly, very easily cause these loop antenna 111 dislocation to link jointly with feed-in device conductor 14, and then influence the effect of antenna receiving-sending radiation, be axes body structure together because of the feed-in device structure 15 of existing antenna again, also be that clad lining 13 and feed-in device conductor 14 are derived and be linearity in axle 10 lower ends and draw, when the electronic building brick in these linear feed-in device structure 15 essential assembling signal amplifiers or the electronic equipment, the shortcoming that electrically connect is difficult for can take place in existing structure equally.

The utility model content

Main purpose of the present utility model, be to provide a kind of feed-in structure improvement of antenna, it utilizes feed-in structure is to form conductive part on the insulating substrate, so that the antenna module on the dielectric carrier easily and feed-in structure electrically connect and can not misplacing, integral body impels the assembling of antenna and feed-in structure more simple and easy, and then significantly promotes the antenna assemblies acceptance rate.

Another purpose of the present utility model utilizes the special construction of feed-in structure to form, and can make feed-in structure be easy to assemble passive component and with the function of balun (BALUN).

Another purpose of the present utility model utilizes the special construction of feed-in structure to form, and can make feed-in structure be easy to assemble required electric circuitry packages in signal amplifier or the electronic equipment.

For achieving the above object, the feed-in structure of the utility model antenna is improved, and it is by a dielectric carrier; One surrounds the antenna module of this dielectric carrier; And one be arranged in the axial channel of dielectric carrier and form with the feed-in structure of antenna module electrically connect, this feed-in structure is to form conductive part on the insulating substrate, and two ends that make insulating substrate lay respectively at the biend of dielectric carrier, so that the antenna module on dielectric carrier one end face can be electrically connect with adjacent conductive portion on the insulating substrate.

After adopting said structure, because insulating substrate and conductive part are a globality structure, so it is very quick and simple and easy to be arranged in the axial passage inside of dielectric carrier, and conductive part is not at same shaft core position, so locality specific of conductive part, therefore, the antenna module on this dielectric carrier top can be distinguished the conductive part electrically connect in addition under the independent contraposition, so electrically linking of the two in conjunction with simple and easy and difficult generation dislocation, integral body can reach assembling fast simple, significantly promote the antenna assemblies acceptance rate.

Embodiment

, the purpose of this utility model, feature and effect further understand and understanding existing detailed description the in detail in conjunction with the accompanying drawings as the back for ease of can being had:

As Fig. 2, Fig. 3, shown in Figure 4, the improvement of the feed-in structure of a kind of antenna of the present utility model, it is by a dielectric carrier 20; One surrounds the antenna module 30 of this dielectric carrier 20; And one be arranged in the axial passage 21 of dielectric carrier 20 and form with the feed-in structure 40 of antenna module 30 electrically connects, wherein this feed-in structure 40 is to form conductive part 42 on the

insulating substrate

41,43,44, and two ends that make insulating substrate 41 lay respectively at the biend of dielectric carrier 20, so that the antenna module 30 on dielectric carrier 20 1 end faces can with adjacent conductive portion 42 on the insulating substrate 41,43 electrically connects, but 44 electrically connects, one signal amplifier 50 of the conductive part on the insulating substrate 41 of these dielectric carrier 20 other ends or electronic equipment (inessential member again, so other electronic building brick not expression in the figure), in addition passive component 60 can be set in the appropriate position of insulating substrate 41, so that feed-in structure of the present utility model 40 produces the function of a balun (BALUN).

Adopt the utility model effect of said structure as follows:

1, feed-in structure 40 of the present utility model is to form conductive part 42 on the

insulating substrate

41,43,44, this insulating substrate 41 can be the printed circuit board (PCB) kenel when implementing, because insulating substrate 41 and
