| Abstract: | The plane-polar near-field measurement basic formulas which are used in calculation of far field pattern are given in this paper. A simplified method used in determining module coefficient of electromagnetic currents is given with the expand way of Jacobi-Bessel series. With the comparision of the consequence of plane-polar near-field measurement of a 1. 2m reflector antenna with the consequence of far-field measurement of this antenna, the efficiency of this method is proved. Meanwhile the advantages are pointed when plane-polar near-field measurement is applied to mesure a large space antenna. |
