Problems solved by technology

[0003] The existing UAV antennas are generally 2.4GHz and / or 5.8GHz microstrip antennas. Low-frequency antennas similar to 900M antennas are gradually being applied to UAVs because of their better receiving gain and anti-interference ability. However, this type of antenna is large in size and can only be placed outside the drone, which affects its use to a certain extent

Embodiment Construction

[0031] 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" and similar expressions are used in this specification for the purpose of description only.

[0032] 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. The terms used in the description of the present invention...

Abstract

The embodiment of the present invention discloses an antenna and an unmanned aerial vehicle. The antenna is disposed inside the unmanned aerial vehicle. The antenna includes a first antenna unit and asecond antenna unit. The first antenna unit and the second antenna unit are disposed on the same surface of a substrate. The first antenna unit includes a first main radiating unit and a first auxiliary radiating unit, and the second antenna unit includes a second main radiating unit and a second auxiliary radiating unit. A gap is disposed between the first main radiating unit and the second mainradiating unit. The first auxiliary radiating unit is connected to a side tail end, far from the second main radiating unit, of the first main radiating unit, and the second auxiliary radiating unitis connected to a side tail end, far from the first main radiating unit, of the second main radiating unit. The first auxiliary radiating unit and the second auxiliary radiating unit are located at the same side of the substrate. In the above manner, the size of the antenna is reduced and the antenna can be installed inside the unmanned aerial vehicle.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of antennas, in particular to an antenna and an unmanned aerial vehicle. Background technique [0002] Antennas are communication components used to transmit or receive electromagnetic waves, and are widely used in wireless communication electronic devices. With the rise of robots and unmanned aerial vehicles and the demand for miniaturization, antennas are constantly developing towards miniaturization. For unmanned aerial vehicles, not only the size of the antenna is required due to the limitation of space, but also the radiation of the antenna is expected to cover all directions evenly. [0003] The existing UAV antennas are generally 2.4GHz and / or 5.8GHz microstrip antennas. Low-frequency antennas similar to 900M antennas are gradually being applied to UAVs because of their better receiving gain and anti-interference ability. However, this type of antenna is large in size and can o...
