The invention belongs to the technical field of unmanned aerial vehicles, and discloses a quad-rotor unmanned aerial vehicle which comprises a fuselage main body, a left rotor wing assembly and a right rotor wing assembly. Each of the left rotor wing assembly and the right rotor wing assembly comprises a first cantilever, a first motor, a first blade and an RTK antenna. A fixed end of the first motor is connected to a lower side of a front end of the first cantilever, the first blade is connected to a movable end of the first motor, and the RTK antenna is arranged on an upper side of the frontend of the first cantilever. The two RTK antennas are arranged at the front end of the left rotor wing assembly and the front end of the right rotor wing assembly respectively, an interval is greatlyincreased compared with that in a previous design, electromagnetic interference of the fuselage main body is prevented, meanwhile, the RTK antennas are arranged on the upper sides of the first cantilevers, the RTK antennas are made to be in a clean electromagnetic environment, and positioning precision is improved. And the first paddle is located right below each RTK antenna so that heat dissipation of the RTK antenna is facilitated.

    本发明属于无人机技术领域,公开了一种四旋翼无人机,包括:机身主体;左旋翼组件和右旋翼组件,均包括第一悬臂、第一电机、第一桨叶和RTK天线,所述第一电机的固定端连接于所述第一悬臂前端的下侧,所述第一桨叶连接所述第一电机的活动端,所述RTK天线设置在所述第一悬臂前端的上侧。两个RTK天线分别设置在左旋翼组件和右旋翼组件的前端,间隔相比之前设计大大增加,同时防止机身主体的电磁干扰,同时将RTK天线设置在第一悬臂的上侧,使RTK天线处于较为干净的电磁环境,提升定位精度;第一桨叶位于RTK天线的正下方,有利于RTK天线的散热。
