Abstract: Disclosed in the embodiments of the present disclosure are an antenna assembly and a communication terminal, where a layout region is arranged at an edge position on a base frame, and a radiation pattern and a parasitic branch are arranged together on the layout region. Thus, in an aspect, when the communication terminal is assembled, it is convenient to observe the connection between a feed point and a ground point of the antenna assembly, thereby improving the assembly efficiency of the communication terminal. In another aspect, a parasitic branch is arranged near a second branch, so that the antenna has a larger bandwidth in a high frequency band. In yet another aspect, configuring a shape of a first slot, a second slot, and the parasitic branch enables direct adjustment to a resonance frequency of the antenna, which improves the adaptability of the antenna to different applications.
