Unmanned aerial vehicle external dual-frequency antenna and unmanned aerial vehicle

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly discloses an unmanned aerial vehicle external dual-frequency antenna and an unmanned aerial vehicle. The unmanned aerial vehicle external dual-frequency antenna comprises a substrate, a low-frequency oscillator area, a high-frequency oscillator area, a feed coaxial line and grounding ends, and the two grounding ends are electrically connected with the feed end of the feed coaxial line; the low-frequency oscillator area or the high-frequency oscillator area is provided with an avoiding area used for arranging the feed coaxial line; the low-frequency oscillator area comprises a first low-frequency oscillator area and a second low-frequency oscillator area; and the high-frequency oscillator area comprises a first high-frequency oscillator area and a second high-frequency oscillator area which are asymmetrically arranged on the front and back surfaces of the substrate up and down. According to the unmanned aerial vehicle external dual-frequency antenna, the first low-frequency oscillator area and the second low-frequency oscillator area, and the first high-frequency oscillator area and the second high-frequency oscillator area are arranged in a positive and negative asymmetrical manner so that the wiring requirement in a relatively small space can be met, the circuit layout is more reasonable, and meanwhile, the signal coverage of dual frequency bands of 2.4 GHz and 5.8 GHz can be met.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an external dual-frequency antenna for an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] With the rapid development of wireless communication and the demand of various data services, antenna design is mainly developed towards miniaturization, multi-band and wide-band. Due to the advantages of compact structure, small size, light weight, low cost, and easy integration with microstrip lines, microstrip antennas are more and more widely used. The microstrip antenna is an antenna composed of a conductor patch attached to a dielectric substrate with a ground plane. It uses a coaxial line to feed the electromagnetic field between the conductor patch and the ground plane, and radiates outward through the gap.

AI Technical Summary

Problems solved by technology

[0003] The existing external dual-frequency antennas of UAVs are generally installed in the tripod, and are generally 2.4GHz and 5.8GHz microstrip antennas. Since the microstrip antennas (such as 900Hz microstrip antennas) working in the low frequency band are relatively small Large, limited by the size of the tripod, cannot be set in the tripod

Although the space size of the UAV arm is larger than that of the UAV tripod, the environment of the UAV arm is more complicated, and it is easy to affect the communication signal of the antenna.
