Abstract

The invention discloses a combined helical antenna and an unmanned aerial vehicle. The combined helical antenna comprises a radiating part, wherein the radiating part comprises a base body and a plurality of radiators, the radiators are arranged on the base body in a surrounding mode in the circumferential direction of the base body, the radiators are arranged in the circumferential direction of the base body at intervals, each radiator comprises at least two extending sections which are connected in sequence, and an included angle is formed between every two adjacent extending sections; the number of the radiation parts is multiple, and the multiple radiation parts are sequentially arranged in the first direction. According to the combined helical antenna, the radiator is integrally bent,so the axial size of the base body is reduced, the size and the weight of the radiation part are reduced, the overall gravity center of the antenna is reduced, and the combined helical antenna is favorably applied to the fields of unmanned aerial vehicles, surveying and mapping equipment and the like with higher requirements on the size and the weight of the antenna; meanwhile, the anti-interference capability, antenna gain and other performance indexes of the whole antenna are excellent, and the antenna can adapt to scenes with complex electromagnetic interference.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a combined helical antenna and an unmanned aerial vehicle. Background technique [0002] With the rapid development of the global navigation satellite system, the traditional single GPS era has gradually transformed into an era of global satellite systems in which multiple navigation systems are compatible and coexist. It is difficult to guarantee the reliability, stability and positioning accuracy of a single satellite navigation system, and the integrated multi-system satellite navigation system will be able to obtain better positioning performance than any single positioning system. Therefore, it has become a trend to develop multi-band antennas that can be compatible with multiple navigation systems at the same time. [0003] As an important part of the satellite navigation receiver, the antenna's performance is directly related to the measurement accuracy of the satellite ...
