In some embodiments, as shown in fig. 3, the first antenna 121 includes a first radiator 1211, the first radiator 1211 is disposed on the first frame 1111 along the first direction, the second antenna 122 includes a second radiator 1221, the second radiator 1221 is disposed on the second frame 1112 along the second direction, wherein a part of the length of the frame 111 may be used as the first radiator 1211, another part of the frame 111 may be used as the second radiator 1221, specifically, the frame 111 may be a metal frame 111, at least a part of the first frame 1111 may be spaced apart from the substrate 112 and form a gap 1116, a through slot 1117 penetrating the gap 1116 is opened on the first frame 1111 to form the first radiator 1211 on the first frame 1111, and similarly, at least a part of the second frame 1112 may be spaced apart from the substrate 112 and form a gap 1116, a through slot 1117 penetrating the gap 1116 is opened on the second frame 1112, to form a second radiator 1221 on the second bezel 1112. Thus, the first bezel 1111 and the second bezel 1112 can be directly used as the first radiator 1211 and the second radiator 1221, so that the first radiator 1211 and the second radiator 1221 are directly exposed, and the strength of transmitting and receiving rf signals is improved.

In some embodiments, as shown in fig. 4, the first bezel 1111 and the second bezel 1112 may be disposed opposite to each other, and the first radiator 1211 and the second radiator 1221 may be disposed in a staggered arrangement or a symmetrical arrangement, for example, the first radiator 1211 may be disposed at one end of the first bezel 1111 and the second radiator 1221 may be disposed at the other end of the second bezel 1111, which is far from the end, so that the first radiator 1211 and the second radiator 1221 may be disposed in a staggered arrangement. By arranging the first radiator 1211 and the second radiator 1221 in the first frame 1111 and the second frame 1112 which are spaced apart from each other, this may increase the distance between the first radiator 1211 and the second radiator 1221, to reduce interference therebetween, and the first radiator 1211 and the second radiator 1221 are disposed to be staggered, the distance between the two can be further increased to further avoid interference between the two, the first frame 1111 and the second frame 1112 can be arranged in a vertical direction, after the intelligent switch 100 is installed on a wall, the first bezel 1111 and the second bezel 1112 face the ceiling and the floor respectively, this prevents the first radiator 1211 and the second radiator 1221 from being located at opposite sides of the smart switch 100 in the horizontal direction, and prevents the first radiator 1211 and the second radiator 1221 from being close to or in contact with adjacent electric devices, thereby preventing interference as much as possible.

By disposing the first radiator 1211 in a first direction and the second radiator 1221 in a second direction substantially perpendicular to the first direction, such that the first radiator 1211 is substantially perpendicular to the extending direction of the second radiator 1221, and thus the polarization directions of the first radiator 1211 and the second radiator 1221 intersect, the isolation between the first radiator 1211 and the second radiator 1221 is increased to reduce mutual interference of signals transmitted and received by the first radiator 1211 and the second radiator 1221.

In addition, in some embodiments, the first radiator 1211 and the second radiator 1221 may be directly disposed on the outer wall of the bezel 111, for example, the outer wall of the bezel 111 may be provided with a groove structure, so that the first radiator 1211 and the second radiator 1221 are embedded on the outer wall of the bezel 111. The first radiator 1211 and the second radiator 1221 may be disposed as decorative parts, for example, the first radiator 1211 and the second radiator 1221 may be disposed in a specific pattern or pattern to be embedded in the bezel 111, so that the first radiator 1211 and the second radiator 1221 are directly exposed, and the light intensity of the transmitted and received rf signals is increased.

In some embodiments, as shown in fig. 3, the first radiator 1211 has a first ground 1213, the second radiator 1221 has a second ground 1223, the first ground 1213 faces the second bezel 1112, and the second ground 1223 faces the first bezel 1111. The end of the first radiator 1211 facing the second bezel 1112 is grounded so that the first radiator 1211 forms a radiation end at the end far from the second bezel 1112, wherein the radiation end of the first radiator 1211 faces the fourth bezel 1114 and can radiate a signal through the through slot 1117 on the first bezel 1111, and the end of the second radiator 1221 close to the second bezel 1112 is grounded so that the second radiator 1221 forms a radiator at the end far from the first bezel 1111, wherein the radiation end of the second radiator 1221 faces the third bezel 1113 and can radiate a signal through the through slot 1117 on the second bezel 1112. The radiation end refers to a portion of the whole radiator where a radiation signal is stronger. This may be as far away from the radiating ends of the first radiator 1211 and the second radiator 1221 as possible, so as to further reduce mutual interference between signals transmitted and received by the first radiator 1211 and the second radiator 1221. Among them, the through slits 1117 and the spacing slits 1116 may be filled with a non-metal material, which may increase the structural strength of the entire housing 110.

In some embodiments, the first radiator 1211 may be disposed at an end of the first bezel 1111 far from the second bezel 1112, and the second radiator 1221 is disposed at an end of the second bezel 1112 far from the first bezel 1111. Thus, the first radiator 1211 and the second radiator 1221 are spaced as far as possible to increase the distance between the first radiator 1211 and the second radiator, thereby increasing the isolation between the first radiator and the second radiator to prevent the signals transmitted and received between the first radiator and the second radiator from interfering with each other. In addition, when the third frame 1113 and the fourth frame 1114 are also provided with antennas, the antenna disposed on the third frame 1113 may be disposed at an end of the third frame 1113 away from the second frame 1112, and the antenna disposed on the fourth frame 1114 may be disposed at an end of the fourth frame 1114 away from the third frame 1113, so that the four antennas disposed on the four frames may be away from each other, and mutual interference between signals transmitted and received by the four antennas is reduced.
