Embodiments of the present invention relate to an antenna unit and antenna. The antenna unit comprises an orthogonal dipole and four feeder pillars; the orthogonal dipole comprises four sets of radial arms and a conductor element with ring-shaped structure, wherein each set of radial arms comprises two or more radial arms connected to each other at inner ends, and the outer ends of the four sets of radial arms are connected to the conductor element with ring-shaped structure; one end of each feeder pillar is connected to the inner ends of a set of radial arms, and the other end is connected to a feed network; the current phases of the two feeder pillars feeding to the two sets of radial arms with the same polarization are opposite of each other. Utilizing the antenna unit and the antenna provided in the present invention can improve polarization purity of the antenna unit. |
