Abstract

Abstract

The spatial power-combination, adopting parabolic antennas as the array cells, has been studied, considering the relation between the spatial power-combination efficiency and the amplitude error and phase error of antenna cells. The results of numerical theoretical analyses and show that the efficiency of spatial power-combination is only related with the amplitude error and phase error of antenna cells only. The simulation on the antenna units and the antenna array shows a spatial power-combination efficiency about 92%.The influencing factors and the improvement methods of the efficiency have been presented．
- spatial power-combination,
- combination efficiency,
- parabolic antenna,
- numerical simulation
