Abstract: An antenna apparatus and a terminal. The antenna apparatus includes an antenna body and at least one stub. The antenna body includes a first branch used to radiate a high-frequency signal and a second branch used to radiate a low-frequency signal. One end of the stub is connected to a connection point of the second branch, and the other end of the stub is a free end. The connection point is a position with a maximum value of current distribution on the second branch of an electromagnetic wave having a wavelength. The wavelength corresponds to a specified high frequency at which the antenna apparatus works. The length of the stub is determined according to the wavelength corresponding to the specified high frequency.
