ABSTRACT:
An omnidirectional antenna provides circular and elliptically polarized electromagnetic waves. The antenna constitutes first and second elements as the only radiating portions of the antenna. Each element has an elongated central portion parallel to each other, with ends bent at a predetermined slant angle above and below horizontal planes running through the central portions, and then with the ends themselves being at acute angles with respect to the central portion. The acute angles of the second element are in opposite orientation to the first. A proper balun is provided for driving the antenna.
