Abstract
A log periodic antenna system with conformal radiating elements includes a feed layer with phase shifters and filters associated with each radiating element. The filters may be low-pass or band-pass filters. The log periodic conformal radiating elements produce superior gain and bandwidth, and reduce directionality of the antenna at least along a radial axis of the antenna. Sets of conformal radiating elements are disposed on opposing sides of the antenna, or periodically around the surface of the antenna, to further reduce directionality.
