Abstract

See full text

An antenna can be joined to an antenna feed and positioned perpendicular to a ground plane. The antenna includes a conductive radiator having a cylindrical portion. A slot is formed in the entire length of the cylindrical portion. Two parallel fins extend from the cylindrical portion at the slot. The fins can extend inwardly or outwardly. The antenna feed is connected to the conductive radiator on either side of the slot. An anisotropic magnetic material having a uniaxial permeability tensor is positioned in the slot between the two fins. This material is oriented such that it has a much greater permeability in the radial direction than in the other directions. The interior of the cylindrical portion can be filled with a dielectric material.
