OMNI DIRECTIONAL CIRCULARLY-POLARIZED ANTENNA

摘要

An omni circularly-polarized antenna comprises: upper and lower layers of metal strips placed horizontally and having identical spoke-like shapes, each of the layers of said metal strips composed of a center and a plurality of spokes connected to the center, the plurality of spokes, at a circumferential position of the spoke-like shape, having extensions extending towards an identical direction along the circumference, wherein extending directions of the extensions of the spokes in the upper and lower layers of metal strips are opposite; metal poles with a number being identical with a number of the spokes in the metal strips, the metal poles vertically interconnecting ends of the extensions of the spokes in the upper and lower layers of metal strips; a coaxial connector comprising an elongated inner conductor and an outer conductor, wherein the elongated inner conductor is connected to the center of the upper layer of metal strip, and the outer conductor is connected to the center of the lower layer of metal strip.
