Embodiment Construction

[0058]In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions are used in this specification for the purpose of description only.

[0059] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. Terms used in the description of the pres...

Abstract

The invention relates to the technical field of unmanned aerial vehicle antennas, and provides an antenna and an unmanned aerial vehicle. The antenna comprises a substrate, an oscillator structure, a director and a feed coaxial line, wherein the oscillator structure is arranged on one side of the substrate, the director and the feed coaxial line are arranged on the other side of the substrate, the oscillator structure comprises a first oscillator with a first resonant frequency and a second oscillator with a second resonant frequency, the feed coaxial line is electrically connected with the first oscillator and the second oscillator respectively, and the director is arranged on one side of the oscillator structure along a first direction. According to the invention, optimal impedance matching of the antenna is achieved by adjusting thefirst oscillator and the layout mode of the first oscillator on the substrate, the directivity of first resonant frequency signal of the first oscillator is improved through the director, the radiation direction of the first resonant frequency is made to deviate towards the working direction, and then the resonant frequency signals in the working direction are adjusted, so that the antenna has directionality at a high frequency band and has good omnidirectivity at a low frequency band.

Description

【Technical field】 [0001] The invention relates to the technical field of drone antennas, in particular to an antenna and an unmanned aerial vehicle. 【Background technique】 [0002] An unmanned aerial vehicle is an unmanned aerial vehicle controlled by radio remote control equipment and its own program control device. As an important part of the UAV system, the wireless communication link system is used to establish an air-to-ground two-way data transmission channel to complete the long-distance remote control, telemetry and mission information transmission of the UAV from the ground control station. [0003] The existing wireless communication link system is generally divided into an airborne part and a ground part. The on-board portion includes the Airborne Data Terminal (ADT) and the antenna. The ADT includes an RF receiver, a transmitter, and a modem for connecting the receiver and transmitter to the rest of the system. The ground segment, also known as the ground data ...
