The housing 1 of the electronic device according to the embodiment of the present application is described below with reference to FIGS. 1 to 6.

As shown in Figures 1 to 6, according to the housing 1 of the electronic device of the embodiment of the first aspect of the present application, the electronic device 100 has an antenna module 3, and the antenna module 3 is provided on the inner side of the housing 1 (the "shell "The inner side of the body 1" refers to the side of the housing 1 adjacent to the center of the electronic device 100).

Specifically, the housing 1 includes a body 11, and the body 11 includes a base 111 and a radiation portion 112. The base 111 is formed with a mounting hole extending through the base 111 along the thickness direction of the base 111, and the cross section of the mounting hole may be circular, polygonal (for example, rectangular), oval, or the like. The radiating portion 112 is installed in the mounting hole, and the size of the radiating portion 112 is adapted to the mounting hole. The radiating portion 112 is suitable for being disposed opposite to the antenna module 3, and the dielectric constant of the radiating portion 112 is smaller than the dielectric constant of the base 111.

When the housing 1 is used in the electronic device 100, since the radiating part 112 is disposed opposite to the antenna module 3, the signal wave emitted by the antenna module 3 basically passes through the radiating part 112 and radiates outward. Since the dielectric constant of the radiating part 112 is smaller than the dielectric constant of the base 111, compared with the signal wave radiating out from the base 111, the loss caused when the antenna module 3 radiates the signal wave can be reduced, thereby improving The gain and efficiency of the antenna module 3 improve the antenna performance of the whole machine. In addition, the material selection of the base 111 can be made more flexible. For example, the base 111 can be made of materials with good mechanical properties, so as to ensure the mechanical properties of the housing 1, for example, the housing 1 can have better structural strength and toughness as a whole. And so on to meet the requirements of use.

Of course, when the antenna module 3 receives a signal, the external signal wave can pass through the radiating part 112 to reach the antenna module 3, and the loss caused when the signal wave passes through the housing 1 can also be reduced, so that the antenna module 3 can receive a stronger signal. Wave, improve the antenna performance of the whole machine.

For example, the base 111 may be a metal piece, a ceramic piece, a glass piece, a resin piece, and the like.

According to the housing 1 of the electronic device of the embodiment of the present application, by setting the body 11 of the housing 1 to include two parts with different dielectric constants, the structure and material selection of the housing 1 can be made more flexible. 3 The relative dielectric constant of the radiating part 112 is small, which can reduce the loss caused when the signal passes through the housing 1. In addition, the material selection of the base 111 can be made more flexible. For example, the base 111 can be made of materials with good mechanical properties, so that the mechanical properties of the housing 1 can be ensured, and the gain and efficiency of the antenna module 3 can be improved.

According to some embodiments of the present application, the dielectric constant of the radiation portion 112 is less than 5. Therefore, when the signal wave passes through the radiating part 112, the loss can be better reduced, and the intensity of the transmitted and received signals can be ensured.
