  • Patent number: 10812205
    Abstract: An antenna performance evaluation method is disclosed. The method includes the following steps: measuring plurality of throughput values of the to-be-tested antenna at the first angle under different average radiation signal-to-interference ratio (SIR). The average radiation SIR and throughput values are fitted to output the first fitted curve. The second throughput value is measured at a certain average radiation SIR of the second angle of the to-be-tested antenna. Calculating a difference value between the first throughput value and the second throughput value corresponding to the same average radiation SIR, and the difference value and the first fitting curve constitute the transition second fitting curve. Selecting different average radiation SIR is repeatedly, and measure the corresponding second throughput value, and the corresponding difference value is calculated to update the transition second fitting curve.
