An antenna test method and apparatus are disclosed. The antenna test method includes: A, placing a mobile terminal on a turntable in an anechoic chamber, and connecting the mobile terminal to a base station emulator via an anechoic chamber communication antenna; B, moving by the turntable sequentially to multiple theta and phi angles, transmitting by the base station emulator signals to the mobile terminal via an anechoic chamber measurement antenna, and receiving and decoding by the mobile terminal the signals and transmitting them back to the base station emulator, to obtain the horizontal and vertical polarization data of the anechoic chamber measurement antenna at steps of a first angle; C, performing interpolations to calculate the corresponding data at steps of a second angle as the step converts from the first angle to the second angle, and using the derived data to calculate the Total Isotropic Sensitivity (TIS).
