In this embodiment, by setting the second antenna 203, and the second frequency band is the same as the first frequency band, when the remote controller 100 is working, the antenna with a stronger signal strength in the first antenna 201 and the second antenna 203 can be selected to work, or when one of the first antenna 201 and the second antenna 203 fails, the other can be selected to work, which is conducive to improving the stability of the remote controller 100. In addition, by rotating the second antenna 203 and connecting it to one end of the second plug-in portion 204, the second antenna 203 can be rotated relative to the controller 1, so that the direction of the radiation signal of the second antenna 203 can be adjusted.

The housing 205 is detachably mounted on the controller 1, and the housing 205 can rotate relative to the controller 1, so as to adjust the direction of the control signal radiated by the first radiating component 206. In addition, since the housing 205 is detachably mounted on the controller 1, when the antenna module 2 needs to be replaced, the first plug-in portion 202 can be detached from the first connecting portion 101 first, and then the housing 205 can be detached from the controller 1.

[0042] In some embodiments, see Figure 5 , Figure 6and Figure 7 The antenna module 2 also includes a second plug-in portion 204 and a second feeder 209.

In this embodiment, the mounting member 210 is fixed to the fixing strip 105 by the first screw connector 211 and the second screw connector 212. When replacing the antenna module 2, the first plug-in portion 202 and the second plug-in portion 204 can be respectively detached from the first connecting portion 101 and the second connecting portion 103, and then the first screw connector 211 and the second screw connector 212 can be removed, and the original antenna module 2 can be removed, which is very convenient.
