Disclosed in the present application are an antenna apparatus and a terminal device. The present application, by means of adding a power attenuator to each antenna unit of an array antenna, and the power attenuators being used to load a Dolph-Chebyshev algorithm and/or a Taylor algorithm so as to attenuate power of an input signal, can effectively inhibit side lobe gain of the array antenna and ensure identical main lobe gain and width.
