摘要：A quadrifilar helix antenna (QHA) operating at 0.94GHz is designed and realized in this paper. The designed QHA consists of four helical conductors which are excited in phase quadrature by employing a Wilkinson divider which shows good performance in return loss and transmission characteristic. According to the designed parameters of the helices and Wilkinson divider, a QHA is fabricated and measured. The measured results demonstrate that the designed QHA has a resonant frequency of 0.94GHz and relative good performances including low voltage standing wave ratio (VSWR), broad beam width and approximate circular polarization are achieved. The designed QHA has simple structure and is suitable for practical application
