Abstract
Characteristics of three coaxial-feed axial mode spherical helical antennas are analyzed by the moment method. The results indicate that gains of the one-arm spherical helical antenna and the hemispherical helical antenna vary acutely in the frequency band and their main beams float from the axial direction when the frequency higher than 1600 MHz. The two-arm hemispherical helical antenna has more than 100% pattern bandwidth and impedance bandwidth, and its gain bandwidth is -93% and the peak gain is 10.7 dB, which shows that it is of great potential value in broadband application
