Description
Technical field
The utility model relates to a kind of antenna, specifically a kind of curved surface multifrequency 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 uses two pieces of antenna overlies mostly respectively, accepts the Big Dipper signal of different frequency range, causes and produces inconvenience, be unfavorable for the problem of large-scale production.
Utility model content
The purpose of this utility model is to provide a kind of curved surface multifrequency 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 multifrequency Beidou antenna, comprise antenna element one, medium, antenna element two and reflecting plate, described antenna element one is positioned at the upper surface of medium, described antenna element two is positioned on the inclined-plane of medium, described medium is taper, described antenna element one and antenna element two feedback point comprises single feed point, double-fed point and four presents point.
As further program of the utility model: also comprise loading low noise amplifier.
As the utility model further scheme: the material of described medium comprises high frequency material and pottery.
As the utility model further scheme: described antenna element two is connected to medium upper surface.
As the utility model further scheme: described antenna operating band comprises GPS, the Big Dipper, Glonass and Galileo.
Compared with prior art, the beneficial effects of the utility model are: the Beidou antenna of different frequency range is focused on a dielectric surface by the utility model, simplifies the structure, is convenient to large-scale production.
Accompanying drawing explanation
Fig. 1 is the front view of curved surface multifrequency Beidou antenna.
Fig. 2 is the vertical view of curved surface multifrequency Beidou antenna.
