One of the notable feature is a single-fed antenna including balun and distributor with 90° phase differential by using four masts with stabs which support two V-dipoles on a reflector. From the port currents of the equivalent circuit of the antenna, a circular polarization condition concerning the configulation of the antenna is obtained. We design the circularly polarized antenna and show the characteristics. It is found that we can optimize the antenna of considerable wide beam in low axial ratio. Validity of this theory is confirmed by an experiment. 收起
