Abstract

See full text

Circularly polarized directional antennas and methods of fabrication are provided. An antenna comprises conductive elements above a conductive reflector. The conducting elements are spaced radially outward from the center axis. The elements may be spaced equidistantly about each other or may be spaced between 10 and 80 degrees apart. The elements may be straight or curved. The elements may be a parallel to the reflector or may curve away or toward the reflector. The lengths and widths of each conductive element are adjusted to create or receive a circularly polarized wave of particular rotation based on the location in the element system. The elements are located within a printed circuit board that is bonded to a coaxial cable feedline placed above a metallic reflector. Each conducting element comprises a metallic wire.
