<p>The antenna may include a planar re-flector having a plurality of loop electrical conduc-tors defining an array of parasitically drivable anten-na elements, and a circularly polarized antenna feed spaced from the planar reflector to parasitically drive the array of parasitically drivable antenna elements and impart a traveling wave current distribution therein. The antenna may have properties that are hybrid between parabolic reflectors and driven ar-rays, providing a relatively compact circularly polar-ized antenna capable of having low wind load. Closed circuit or loop elements may provide in-creased gain over antennas using dipole turnstile re-flector elements.</p> |
