Improved variable length slot fed dipole antenna

摘要

A slot fed antenna for use in radiating energy, the antenna including 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 dipole wing element 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.
