| Abstract: | A novel feed of broad-band circularly polarized spherical helical is presented.Compared with conventional circularly polarized feed,the novel one has many advantages,such as simple structure,broadband,small size and so on.In the investigation,the geometric relation of the spherical helical is given,by theoretical analyse the analytic expression of radiation field and far-field for different modes.Based on these theories,the feed for engineer is designed and tested.The results prove the approach could be use... |
