Problems solved by technology

[0003] The external tri-band antenna of the UAV under the existing technology, because the frequency of the low frequency band and the middle frequency band in the three frequency bands (978MHz, 1.09GHz, 5.8GHz) is close, so the layout of the vibrator circuit is relatively complicated, and then it is also very complicated. It is difficult to make the antenna structure design more compact

Abstract

The invention belongs to the technical field of communication, and particularly discloses an external three-frequency antenna of an unmanned aerial vehicle, wherein the external three-frequency antenna comprises a substrate, oscillator circuits and a feeder line, and the oscillator circuits are laid on the substrate and comprise a high-frequency oscillator circuit, an intermediate-frequency oscillator circuit and a low-frequency oscillator circuit; a common microstrip line is arranged between the medium-frequency oscillator circuit and the low-frequency oscillator circuit; the feeder line comprises a first feeder line and a second feeder line, and the first feeder line is connected with the high-frequency oscillator line; and the second feeder line is connected with the common microstrip line, and a capacitor is arranged at the joint of the second feeder line and the common microstrip line. The external three-frequency antenna of the unmanned aerial vehicle with the structural design is compact in circuit layout and good in gain effect, and can effectively meet the use requirements of high, medium and low frequency bands.

Description

technical field [0001] The invention relates to the communication technology field, in particular to an external tri-band antenna for a drone. Background technique [0002] In UAV communication applications, the communication load usually requires the antenna of the mobile communication terminal to have performance characteristics such as multi-band, high gain, and large bandwidth to meet the communication requirements, and as the development of mobile terminals tends to be miniaturized, the antenna size is proposed higher requirements. [0003] The external tri-band antenna of the UAV under the existing technology, because the frequency of the low frequency band and the middle frequency band in the three frequency bands (978MHz, 1.09GHz, 5.8GHz) is close, so the layout of the vibrator circuit is relatively complicated, and then it is also very complicated. It is difficult to make the antenna structure design more compact. Contents of the invention [0004] The purpose o...
