Abstract

The invention provides a helical antenna for an unmanned aerial vehicle. The helical antenna for the unmanned aerial vehicle comprises a carrier and at least four radiation arm groups, wherein each radiation arm group comprises a long arm radiation arm, a short arm radiation arm, a small short arm, a coupling arm and a feed point; every two long arm radiation arms are connected through one coupling arm; each short arm radiation arm is coupled by loading one small short arm; the radiation arm groups are printed on a flexible PCB; and the flexible PCB winds the carrier, and is fixed on the carrier through a reserved capacitor bonding pad. The helical antenna for the unmanned aerial vehicle provided by the embodiment is simple to assemble, easy to mount on the unmanned aerial vehicle, and capable of improving antenna receiving frequency bandwidth and gain bandwidth.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an unmanned aerial vehicle helical antenna. Background technique [0002] Global Navigation Satellite System (GNSS) has the characteristics of all-time, all-weather, high-precision, continuous and real-time navigation, positioning and timing, so it plays an increasingly important role in economic development, scientific research, disaster prevention and control, and military fields. increasingly important role. In recent years, the development of high-precision unmanned aerial vehicles and handheld high-precision mobile measurement equipment has become faster and faster, and these devices require antennas with wide bandwidth, high precision, and strong satellite search capabilities to achieve high-precision measurement functions. However, the traditional patch microstrip antenna is difficult to meet the needs of mobile high-precision measurement equipment due to its large size, heavy wei...
