Embodiment
[0025] see Figure 1-4 As shown, a horizontal omnidirectional circularly polarized antenna provided by the embodiment of the present invention includes a base plate 1, an output connector 2 disposed on the lower end of the base plate 1, a vertically polarized antenna 3 disposed on the upper end of the base plate 1, and a vertically polarized antenna 3 disposed on the base plate 1. The upper end is sleeved on the polarized radome 4 outside the vertically polarized antenna 3. The output connector 2 passes through the bottom plate 1 and is connected to the vertically polarized antenna 3. The shape of the polarized radome 4 is a hollow tube, and the vertically polarized The antenna 3 is located at the axial center of the polarized radome 4, and the outer surface of the polarized radome 4 is obliquely covered with a plurality of metal polarization grids 5, and the plurality of metal polarization grids 5 are arranged in sequence and form a grid-like spiral Spin up.
