Abstract
The invention discloses a GNSS (Global Navigation Satellite System) antenna array. The GNSS antenna array comprises a high-frequency medium; a reflective plate is arranged on the lower surface of the high-frequency medium; antenna elements A, B, C, D, E, F, G and H arranged in an array are installed on the upper surface of the high-frequency medium; the antenna elements A, C, E and G belong to the same frequency points; the antenna elements B, D, F and H belong to the same frequency points; and couplers are connected between the antenna element A and the antenna element B, between the antenna element C and the antenna element D, between the antenna element E and the antenna element F, and between the antenna element G and the antenna element H, so that four sets of signals are output. The GNSS antenna array disclosed by the invention is simple in structure, reasonable in design, high in antenna element integration level and good in low-elevation gain effect; good reception can also be ensured even a complex section; compared with the existing antenna, the production cost is not increased; the production difficulty is low; and thus, the GNSS antenna array is applicable to large-range application.
Description
Technical field
The present invention relates to technical field of satellite navigation, specifically a kind of GNSS aerial array.
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 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 antenna unit integrated level is low, and low elevation gain is poor, causes in complicated highway section reception condition not good.
Summary of the invention
The object of the present invention is to provide a kind of GNSS aerial array, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of GNSS aerial array, comprises high-frequency dielectric; Described high-frequency dielectric lower surface is provided with reflecting plate, high-frequency dielectric upper surface is provided with antenna element A, antenna element B, antenna element C, antenna element D, antenna element E, antenna element F, antenna element G and antenna element H, described antenna element A, antenna element B, antenna element C, antenna element D, antenna element E, antenna element F, antenna element G and the arrangement of antenna element H array.
As the further scheme of the present invention: described antenna element A, antenna element C, antenna element E and antenna element G are same frequency, antenna element B, antenna element D, antenna element F and antenna element H are same frequency.
As the present invention's further scheme: described antenna element A and antenna element B, antenna element C and antenna element D, antenna element E and antenna element F, antenna element G and antenna element H each other butt coupling device export 4 groups of signals.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is simple, and reasonable in design, antenna element integrated level is high, and low elevation gain is effective, even if complicated highway section also can ensure good reception.Relative to existing antenna, production cost does not increase, and production difficulty is low, is applicable to using on a large scale.
