ABSTRACT:
A multi-element directional antenna and process for making same are described. The antenna comprises a lightweight dielectric substrate having an array of parasitic elements disposed on the substrate. A printed circuit board having a ground plane on one side thereof, and a driven element and phasing means comprising a hybrid (magic-or-twin) tee junction on the other side thereof, disposed coplanar with the parasitic elements and the substrate. The multi-element directional antenna, may be formed using low labor cost manufacturing process such as stamping and laminating, and additive and/or subtractive (i.e. etching) techniques.
