Description
Technical field
The utility model relates to field of antenna, particularly relates to a kind of helical antenna.
Background technology
Along with constantly improving and the continuous lifting of social life level of each measuring system, hi-Fix has developed to obtain relative maturity, and wisdom traffic, precision agriculture have become much-talked-about topic, is also the inexorable trend of civil nature of navigating from now on.Especially in the application such as agricultural machinery, handheld device, develop to low side common apparatus from original high-end special equipment in big strides, and presented low-end application trend.
Meanwhile, along with the development of China's Beidou satellite navigation system and Galileo system, the monopoly position of gps system has been broken.Along with the construction of the autonomous satellite navigation system of China is perfect, multi mode terminal equipment will be widely applied.
In addition, four-arm spiral antenna has the when excellent circular polarization characteristics in cardioid directional diagram, good front and back because of it, be considered to desirable global position system GPS and satellite mobile phone reception antenna, but volume is greatly its obvious shortcoming.
Therefore, the high accuracy of antenna has become current hot technology with Miniaturization Research.
Utility model content
The purpose of this utility model is, provides a kind of helical antenna, with the problem improving the miniaturization of existing helical antenna, broadband, multifrequency point cannot be taken into account.
The utility model discloses a kind of helical antenna, comprise the spiral arm that base and 4 are arranged on the carrying aerial radiation main body on base; Above-mentioned spiral arm comprises principal arm and parasitic, and the bottom of above-mentioned parasitic is connected by metal connector with the bottom of above-mentioned principal arm.
Preferably, above-mentioned aerial radiation main body is printed on flexible media plate;
Preferably, above-mentioned principal arm and parasitic are positioned on the same face of cylinder;
Preferably, above-mentioned principal arm and parasitic are positioned on the different faces of cylinder;
Preferably, the angle between above-mentioned metal connector and base is adjustable.
The utility model, by regulating position and the length of the sheet metal connecting principal arm and parasitic, achieves antenna multifrequency, frequency is many; The radiating principal of antenna is printed on flexible media plate, and the volume of antenna is significantly reduced.
