Wideband antenna

Abstract

A monoconical antenna comprises: a substantially conical radiation electrode; and a ground conductor provided in proximity to said radiation electrode, and is so constituted that electrical signals are fed to between the near vertex region of said radiation electrode and the region of said ground conductor, wherein the straight line connecting the vertex of said substantially conical radiation electrode and the center of the base of the cone is not perpendicular to the base of the cone and a conical antenna comprising: an insulator;a substancially conial concavity provided in one end face of said insulator;a radiation electrode formed on the internal surface of said concavity;a stripped portion obtained by circumferentially stripping part of said radiation electrode;a low-conductivity member filled in said concavity to the level at which at least said stripped portion is buried; anda ground conductor provided in proximity to and substantially in parallel with the other end face of said insulator or formed directly on the other end face of said insulator.
