In this embodiment, the rear housing assembly 20 includes a non-metallic rear housing 201 and a metal part 202, which may be plate-shaped or bar-shaped, and for example, includes at least one of a metal plate body and a metal bracket. The provision of the metal member 202 in the non-metal back case 201 can improve the strength of the non-metal back case 201 due to the greater hardness of the metal. The non-metal rear case 201 may be any rear case made of a non-metal material, such as a plastic rear case. The metal member 202 may be made of any metal material such as aluminum, magnesium, or stainless steel. In an embodiment, the material of the metal component 202 may be aluminum, and firstly, the aluminum material has a large electrical conductivity and a large thermal conductivity, which is helpful for heat dissipation of the communication terminal; secondly, aluminum is non-ferromagnetic and does not affect the signal of the communication terminal; finally, aluminum is not pyrophoric, which reduces the probability of a communication terminal catching fire if the communication terminal overheats.

The antenna assembly 30 is disposed in a first region S1 of the non-metallic rear housing 201. in this embodiment, the first region S1 is disposed on a side of the non-metallic rear housing 201 facing the front housing assembly 10. after the front housing assembly 10 and the rear housing assembly 20 are mated, the antenna assembly 30 is disposed between the front housing assembly 10 and the rear housing assembly 20. therefore, the first region S1 is shown in dashed lines in fig. 1 and 2 to indicate that the first region is not visible from both the front view and the rear view.
