[Abstract]:In this paper, the calculation models of plane near-field test distance and truncation error are established. The far-field pattern of antenna is calculated by direct calculation method and near-far field transformation method from near-field data, the calculation results are given, and the influence of test distance and truncation level on the test results in plane near-field test is analyzed.
