| Abstract: | The far field patterns of several types of antennas had been discussed by means of PWS and FDTD methods respectively. And through the comparisons of results, we analyzed the effects of sampling plane to far field, demonstrated the applicability of PWS theory to high and low directivity antennas , so that we can further researchthe error analysis and correction. |
