ANTENNA, GROUND CONTROL SYSTEM OF UNMANNED AERIAL VEHICLE, AND UNMANNED AERIAL VEHICLE SYSTEM

摘要

Provided are an antenna, a ground control system of an unmanned aerial vehicle, and an unmanned aerial vehicle system. The antenna (100) comprises a substrate (1), a plurality of dipoles (2) printed on the substrate, a feed network (3) and an earth plate (4), wherein each of the dipoles (2) comprises an element unit (20) arranged at one side of the substrate (1), and an element unit (20) arranged at the other side of the substrate (1), and each element unit (20) comprises a first element (21) and a second element (22); the feed network (3) is connected to each element unit (20); and the substrate (1) and the earth plate (4) are arranged in parallel at an interval of pre-set distance. The antenna in the embodiments of the present invention has good matching performance and radiation performance, the gain of the antenna is increased, and the data transmission distance is long.
