Abstract: In this paper, a new spherical helical antenna, which has relatively small FaNr}$Pe  
volume and high gain value, is researched. Their radiation characteristics and input mBQA~@}  
impedance at two different modes are presented. A new half spherical helical antenna O] T'\6w  
at the axial-null mode is presented first here, which has smaller volume and provides l[Hgh,  
perfect shaped-conical, is suitable for LEO satellite communication. P;.j5P^j`
