Abstract
A folded back doublet antenna including two symmetrical half-plates separd at their one ends by a cut, a long, continuous plate separated from one side of each of the half-plates by a gap, linking sections joining the other external ends of the half-plates to respective ends of the continuous plate, and a line feeding the antenna in the vicinity of the cut and extending along the axis of symmetry of the half-plates. The half-plates have a common width, which is much larger than the width of the continuous plate. The half-plates constitute an input side and the continuous plate constitutes a folded back side.
