The side plates 22 of the floor panel 20 may be integrally formed with the bottom panel 21, or may be fixed to the bottom panel 21 by a connecting member, such as a screw. The side plates 22 may be disposed at two opposite side edges of the bottom plate 21, and form a U-shaped ground plane 20 together with the bottom plate 21. Optionally, in order to achieve good grounding of the circuit board, the bottom plate 21 and the side plate 22 of the ground plane plate 20 are both conductive metal plates. It is understood that the ground plane 20 may be made of other conductive materials.
