Abstract

An antenna assembly, a ground plate and an unmanned aerial vehicle. The antenna assembly comprises an antenna, an antenna circuit board matching the antenna, and a ground component, wherein the antenna circuit board is connected to the antenna; a metal shielding cover is arranged on the antenna circuit board; the metal shielding cover is connected to a ground line in the antenna circuit board; the ground component comprises a ground plate with conductive performance; and the ground plate is electrically connected to the metal shielding cover so as to improve the gain of the antenna in the antenna assembly.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an antenna assembly, a grounding component and an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned carrier controlled by radio remote control equipment, such as unmanned aerial vehicles, unmanned vehicles, unmanned ships, etc. Due to the advantages of small size and flexible maneuverability of UAVs, UAVs are used in many Wide range of applications in this technical field. [0003] In actual use, in order to realize the positioning of the UAV, it is necessary to install a Global Positioning System (GPS) antenna on the UAV, and the GPS antenna realizes the positioning of the UAV by receiving satellite signals. In most technical fields, such as military and scientific research technology, the accuracy of UAV positioning is required to be high, which requires the GPS antenna installed on the UAV to have a high gain. However, in the prior art, due to Due to...
