Variable length slot fed dipole antenna

摘要

A slot fed antenna is disclosed for use in radiating energy. The antenna includes a flat conductive member having an elongated vertically- oriented slot dividing the member into a pair of horizontally- extending variable-length flat dipole wing elements. Each of the flat dipole wing elements has a vertically-extending rectilinear edge. Also, each wing element extends in width in a direction perpendicular to the rectilinear edge from a minimum at its center and at each of its upper and lower ends to a maximum midway between each of the ends and the center.
