Abstract
The utility model discloses a kind of curved surface Beidou antenna, comprise antenna element, high-frequency dielectric and circuit board, described antenna element is positioned at high-frequency dielectric upper surface, described circuit board is positioned at high-frequency dielectric lower surface, described antenna element is sprayed on curved surface, the feedback point of described antenna element on curved surface comprises center of surface position, also comprises loading low noise amplifier.The utility model volume is little, and high integration multifrequency covers, and the low elevation angle is high.
Description
Technical field
The utility model relates to a kind of antenna, specifically a kind of curved surface Beidou antenna.
Background technology
Beidou satellite navigation system is global positioning satellite and the communication system of China's independent research.With GPS of America, Russian Ge Luonasi, European Union's Galileo system be called global four large satellite navigation system.At present, these 4 systems are confirmed as GPS (Global Position System) core supplier by the United Nations together.It changes the situation that China lacks high accuracy, in real time positioning means for a long time, break the U.S. and the Russia monopoly position in this field, can be China land, ocean, all kinds of military and civilians that are aerial and space provide multiple business guarantee, especially the modernization of raising China's national defense is had great significance.
China's Beidou satellite navigation system is the GPS (Global Position System) of China's independent research, autonomous operation, can be widely used in the every field of economic society, is the important space information infrastructure that country is building.This system is applied at numerous areas such as mapping, fishery, communications and transportation, telecommunications, water conservancy, forest fire protection, the mitigation disaster relief and national security, creates significant economic benefit and social benefit.
Since dipper system is towards since civilian, there is the hand-hold type Big Dipper terminal of the multiple frequency range of multiple compatibility; And the Big Dipper terminal that a compatible Big Dipper generation is received and dispatched, Beidou II receive frequency comprises such five frequencies of GPS (L1) frequency, because compatible frequency causes antenna size larger more, or the difficulty that minification increases making the spacing of cracking of antenna element less in production technology, hinders the broader applications of multifrequency dipper system.Current Big Dipper application antenna volume is comparatively large, and antenna element integrated level is low, and low elevation gain is poor, causes in complicated highway section reception condition not good.
Utility model content
The purpose of this utility model is to provide a kind of curved surface Beidou antenna, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of curved surface Beidou antenna, comprise antenna element, high-frequency dielectric and circuit board, described antenna element is positioned at high-frequency dielectric upper surface, and described circuit board is positioned at high-frequency dielectric lower surface, and described antenna element is sprayed on curved surface.
As further program of the utility model: described antenna operating band comprises GPS, the Big Dipper, Glonass and Galileo.
As the utility model further scheme: the feedback point of described antenna element on curved surface comprises center of surface position.
As the utility model further scheme: also comprise loading low noise amplifier.
Compared with prior art, the beneficial effects of the utility model are: volume is little, and high integration multifrequency covers, and the low elevation angle is high.
Accompanying drawing explanation
Fig. 1 is the front view of curved surface Beidou antenna.
Fig. 2 is the vertical view of curved surface Beidou antenna.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of curved surface Beidou antenna, comprise antenna element 1, high-frequency dielectric 2 and circuit board 3, described antenna element 1 is positioned at high-frequency dielectric 2 upper surface, described circuit board 3 is positioned at high-frequency dielectric 2 lower surface, described antenna element 1 is sprayed on curved surface, in order to coordinate various environment, again antenna element 1 can be slotted, adjustment frequency position, described antenna operating band comprises GPS, the Big Dipper, Glonass and Galileo, meet wider band designs demand, the feedback point of described antenna element 1 on curved surface comprises center of surface position, described curved surface Beidou antenna, also comprise loading low noise amplifier, can the high-quality signal of stable output.
The Beidou antenna that the utility model provides has the curved surface Beidou antenna that volume is little, high integration multifrequency covers, the low elevation angle is high.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
