Description
Technical field
The utility model relates to antenna, especially GNSS (Global Navigation Satellite System) antennas.
Background technique
In existing survey field, the design scheme of high-acruracy survey GNSS antenna generally use stacked microstrip antenna,
Two kinds of element antenna, although can satisfy actual application demand in technical field, face city fiercer at present
Competition, under the premise of properties of product guarantee, the cost control for product is a competitive advantage of most critical, therefore needle
A performance can be designed to the design feature of existing GNSS antenna to satisfy the use demand, lower-cost novel product.
Utility model content
The technical problem that an aspect of this disclosure solves is, provides a kind of improved GNSS antenna.
The technical scheme adopted by the utility model to solve the technical problem is as follows: novel belt spurious resonance ring broad-band antenna,
The antenna includes that pcb board, gradual change radiator and parasitic part, the pcb board are equipped with corresponding with the gradual change radiator
Feeding network, there are four the contact portion being turned over downwards, each contact portion feeds corresponding with one for the gradual change radiator tool
Network connection, the parasitism part are located on the gradual change radiator periphery, and the parasitism part is connected to by several short-circuit column supports
On the pcb board.
Foregoing novel belt spurious resonance ring broad-band antenna, the parasitism part are annular in shape.
Foregoing novel belt spurious resonance ring broad-band antenna, each short-circuit column be all made of screw and the pcb board,
The parasitism part is fixedly connected.
Foregoing novel belt spurious resonance ring broad-band antenna, the gradual change radiator are the plate knot of foreign white copper material
Structure, with a thickness of 0.2mm.
An aspect of this disclosure bring one is the utility model has the advantages that improved antenna is simplified by the topology layout of optimization
Installation, is effectively reduced production cost.
Detailed description of the invention
Some specific realities of the utility model are described in detail by way of example and not limitation below in conjunction with attached drawing
Example is applied, identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.
In attached drawing:
Fig. 1 is utility model diagram；
Fig. 2 is the utility model perspective view of the explosion；
Mark is described as follows in figure:
1, gradual change radiator；2, parasitic part；3, short-circuit column；4, pcb board.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, described
Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.
Based on described the embodiments of the present invention, those of ordinary skill in the art are before without creative work
Every other embodiment obtained is put, is fallen within the protection scope of the utility model.Unless otherwise defined, the disclosure uses
Technical term or scientific term should be the personage in the utility model fields with general technical ability understood it is logical

System, after the absolute position for being described object changes, then the relative positional relationship may also correspondingly change.
Refering to fig. 1-2, it show the GNSS antenna of novel belt spurious resonance ring width band, the antenna includes pcb board 4, gradually
Become radiator 1 and parasitic part 2, the pcb board 4 are equipped with feeding network corresponding with the gradual change radiator 1, the gradual change
There are four the contact portion being turned over downwards, each contact portion feeding networks corresponding with one to connect (i.e. transmission network for the tool of radiator 1
Network is four), the parasitism part 2 is located on 1 periphery of gradual change radiator, and the parasitism part 2 is connected by several short-circuit supports of column 3
It is connected on the pcb board 4.
The workflow of antenna are as follows: gradual change radiator 1 and parasitic part 2 mainly receive satellite-signal, and short-circuit column 3 mainly rises
Satellite signal transit to the pcb board 4 with feeding network will be received by each feeding network to the effect of transmission signal
Satellite-signal amplification, then filter out the signal other than satellite band with postfilter by the way that antenna is preposition, leave satellite letter
Number useful frequency range part, meets the requirement of satellite receiver.
The parasitic part 2 of its in the improved GNSS antenna of this case is hollow to ensure to be located at 1 periphery of gradual change radiator with ring,
Pass through the short-circuit support of column 3 with pcb board 4 to connect, thus forms enough spaces to install gradual change radiator 1, become between structure
Must be more compact, avoid excessively dispersion from increasing occupied space.Gradual change radiator 1 forms contact in such a way that partial region turns down
So as to subsequent processing, which makes technique more simplified in portion, effectively reduces cost, and the contact portion after turning down can pass through weldering
The connection for connecing technique realization and the feeding network that meets guarantees the stability of connection.
Annular shape can be used in the parasitic formation of part 2, the gradual change radiator 1 of plate is arranged in its circular inner ring, gradual change
The material of radiator 1 can be foreign white copper, and thickness is preferably 0.2mm, is also convenient for carrying out while meeting process of signal transmission
Fold operation.Short-circuit 3 both ends of column can be fixed with gradual change radiator 1, pcb board 4 by screw respectively, easy to operate, peace
Dress is reliable.
To sum up, improved GNSS antenna, which has, installs the high feature of simple, integrated degree, is directed in material
The carry out material Selection and Design of property, complete machine are at low cost, light-weight.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, the utility model can have various changes, combination and variation.It is all the utility model spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should be included in the utility model scope of the claims it
It is interior.
