Problems solved by technology

Therefore, when the distance between the UAV and the ground control system is relatively long or there are obstacles between the UAV and the ground control system, the data transmitted by the omnidirectional antenna of the ground control system cannot reach the UAV smoothly, resulting in ground control problems. The system loses contact with the drone

Abstract

The present invention provides an antenna, a ground control system for an unmanned aerial vehicle, and an unmanned aerial vehicle system, wherein the antenna (100) includes a substrate (1), a plurality of dipoles (2) printed on the substrate, A feed network (3) and a grounding plate (4), the dipole (2) includes an oscillator unit (20) arranged on one side of the substrate (1) and an oscillator unit (20) arranged on the other side of the substrate (1) The oscillator unit (20), wherein the oscillator unit (20) includes a first oscillator (21) and a second oscillator (22); the feed network (3) is connected to each oscillator unit (20); the The base plate (1) and the grounding plate (4) are arranged in parallel with a preset distance. The antenna of the embodiment of the present invention has good matching performance and radiation performance, improves the gain of the antenna, and has a long data transmission distance.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to an antenna, a ground control system of an unmanned aerial vehicle and an unmanned aerial vehicle system. Background technique [0002] In the field of drones, omnidirectional antennas are generally used to transmit data (such as control commands, images, etc.) between the drone and the ground control system. Among them, the omnidirectional antenna is generally in the form of a dipole or a circularly polarized omnidirectional antenna similar to a dipole. Due to the gain characteristics of this type of antenna, the data transmission distance is relatively short. Therefore, when the distance between the UAV and the ground control system is relatively long or there are obstacles between the UAV and the ground control system, the data transmitted by the omnidirectional antenna of the ground control system cannot reach the UAV smoothly, resulting in ground control problems. The system...
