The utility model discloses simple structure, reasonable in design utilizes array geometry to combine 4 group's antenna elements, has improved buff, has compensatied the shortcoming of the low gain of simple helical antenna. The utility model discloses low in cost, production simple process is fit for using on a large scale.
Description
Technical field
The utility model relates to technical field of satellite navigation, specifically a kind of helical array 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 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 helical antenna gain is low, is unfavorable for that antenna carries out high accuracy use.
Utility model content
The purpose of this utility model is to provide a kind of helical array 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 helical array antenna, comprises reflecting plate; Described reflecting plate is provided with antenna element A, antenna element B, antenna element C and antenna element D, antenna element A, antenna element B, antenna element C and antenna element D are array arrangement.
