Abstract
An object of the invention is to provide a fan-beam antenna which comprises a flare which is long in a horizontal direction thereof and whose cross section is horn-shaped, and a water-proof box housing components of said antenna, in which a vertical beam width is made narrow without spreading a vertical size to increase gain. Accordingly, this invention is characterized in that a radome radiation surface is constituted of a plurality of dielectric plates equivalently, and at least one of the dielectric plates is made a dielectric lens having a characteristic similar to a convex lens.
