Abstract
The invention discloses a four-arm Archimedean antenna which comprises a first antenna element, a second antenna element, a third antenna element, a fourth antenna element, a first feed-pin, a second feed-pin, a third feed-pin, a fourth feed-pin and a floor, wherein the first feed-pin, the second feed-pin, the third feed-pin and the fourth feed-pin are mounted on the floor; the first antenna element, the second antenna element, the third antenna element and the fourth antenna element are located above the floor; the first antenna element is connected with the first feed-pin, the second antenna element is connected with the second feed-pin, the third antenna element is connected with the third feed-pin, and the fourth antenna element is connected with the fourth feed-pin. The four-arm Archimedean antenna disclosed by the invention not only can be used for navigation, but also can be applied to other aspects such as radio frequency identification and the like, so that the problem that the antenna is short in width is solved. Circular polarization with the different of the phase of 90 degree is formed through the first antenna element, the second antenna element, the third antenna element and the fourth antenna element in four different phases, so that the cost is lowered. The same performance can be accomplished by a single high frequency material, so that the effect of the antenna disclosed by the invention is superior to that of a conventional antenna.
Description
Technical field
The present invention relates to a kind of antenna, specifically a kind of four arm Archimedes antennas.
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, this four systems is 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 compatible Big Dipper generation transmitting-receiving, Beidou II receive frequency comprises again the Big Dipper terminal of 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, hinder the broader applications of multifrequency dipper system, namely current Beidou navigation adopts large scale to realize the high accuracy of antenna substantially, the laminated construction of basic employing two pieces of antennas, and performance is not well positioned to meet now growing communication needs, and bandwidth is narrower, price is higher, assembling aspect is more complicated.
