Abstract
A circularly polarized omnidirectional antenna consisting of a vertical sleeve dipole and three pairs of tilted parasitic elements set around it is proposed. The antenna has a simple structure and no feeding network for radiating circular polarization. The authors describe the idea of the proposed antenna, some experimental approaches and the evaluation of the antenna by using the moment method.
