In alternative embodiments, the antenna slot 212 may also be opened at the windward end or the leeward end of the antenna radome body 210.

In the present embodiment, the antenna slot 212 extends along the length direction of the antenna radome body 210. Because antenna radome body 210 sets up the upper surface at fuselage 100 on standing, consequently set up the extending direction of antenna groove 212 to be unanimous with antenna radome body 210's length direction, can make unmanned aerial vehicle 010 in the normal driving process, antenna 202 is the state of erectting, is favorable to the receiving and dispatching of signal. It is understood that in alternative embodiments of the present application, the antenna slot 212 may be angled or even perpendicular to the length of the radome body 210. In the present embodiment, one end of the antenna slot 212 in the longitudinal direction extends out from the end where the antenna radome body 210 is connected to the body 100, so that the line of the antenna 202 is led out from the antenna radome body 210.

As shown in fig. 5, the antenna slot 212 includes two portions, namely a first groove 213 opened on the surface of the cowling main body 211 and a second groove 214 opened at the bottom of the first groove 213, and the first groove 213 is adjacent to the surface of the cowling main body 211, so that the opening of the antenna slot 212 is formed in the first groove 213. The second recess 214 is adapted to the outer shape of the antenna to accommodate at least a portion of the antenna 202, and the cover 215 is fitted into the first recess 213 to close off the opening of the antenna slot 212.

To keep the antenna radome body 210 surface smooth, the outer surface of the cover 215 matches the outer surface shape of the radome body 211. Since the antenna 202 in the embodiment of the present application is cylindrical, in order to fit the shape of the antenna 202 and prevent the antenna 202 from shaking in the antenna slot 212, the cross section of the second groove 214 is semicircular to fit the surface of the antenna 202. The cover 215 is fitted into the first groove 213, and similarly to improve the stability of the antenna 202, a third groove 216 adapted to the outer shape of the antenna 202 is provided inside the cover 215, and the cross section of the third groove 216 is also semicircular and can be fitted to the outer shape of the antenna 202. It should be understood that in alternative embodiments, the shape of the antenna 202 is not limited to a cylinder, and thus the specific shapes of the second groove 214 and the third groove 216 of the cover 215, which are adapted to the external shape of the antenna 202, are set according to the specific shape of the antenna 202.

In order to reduce the weight of the unmanned aerial vehicle 010, in the present embodiment, the antenna radome body 210 is made of a material that is light and has good wave-transmitting ability, such as foam.

Since the antenna radome body 210 may not be easily formed of a material having a good smoothness, the roughness of the outer surface of the antenna radome 201 is reduced by covering the antenna radome body with the smooth film 217, thereby reducing wind resistance. In this embodiment, the seams of the smooth film 217 are located at the leeward end 201b to minimize additional wind resistance caused by irregularities at the seams. Alternatively, the smooth film 217 may be made of a material having a high surface smoothness and being transparent to waves.

In embodiments where the radome 201 includes a smooth film 217, the radome 201 may be assembled by first attaching the cover 215 to the radome body 211 and then wrapping the radome 201 with the smooth film 217.

In alternative embodiments of the present application, the antenna radome body 210 may not be covered with the smooth film 217 if the outer surface of the antenna radome body 210 is sufficiently smooth.

In an alternative embodiment of the present application, the antenna assembly 200 is assembled by first installing the antenna 202 on the main body of the drone, then sleeving the radome 201 on the antenna 202, and finally fixing the radome 201 on the main body of the drone.

After the antenna 202 is installed, the antenna radome 201 is sleeved on the antenna 202, and the antenna radome 201 is fixed to the main body of the unmanned aerial vehicle through an adhesive.

In alternative embodiments of the present application, the antenna radome 201 may further include other structural designs adapted to the antenna 202, such as a wire hole for passing a wire of the antenna 202, a connection structure (e.g., a mounting hole) for connecting to a main body of the drone, and the like.

The antenna 202 may be secured within the antenna slot 212 by an adhesive. The adhesive not only fastens the antenna 202 and the interface, but also bonds and fixes the antenna 202, the antenna interface and the antenna slot 212 together, so that the antenna 202 is less prone to shaking relative to the antenna radome body 210. Alternatively, the antenna interface may be disposed on the main body 100, and when the antenna assembly 200 is mounted, the antenna fairing body 210 is disposed at a position corresponding to the antenna interface, so that the antenna interface passes through the lower end opening of the antenna slot 212 in the embodiment shown in fig. 4, and extends into the antenna slot 212 or is opposite to the inner cavity of the antenna slot 212, and then the antenna 202 is disposed in the antenna slot 212 and connected to the antenna interface. Finally, the cover 215 and the smooth film 217 are mounted, completing the mounting of the antenna assembly 200.

Since the size of the radome body 210 in the thickness direction thereof is small, it is similar to a plate shape, and the wind resistance can be reduced to some extent. At least one surface in the thickness direction is a streamline curved surface which is arched outwards, so that the antenna fairing body 210 has a certain space for installing the antenna 202, and the streamline curved surface has a better aerodynamic shape and can reduce wind resistance as much as possible.
