Abstract
An omni-directional, multi-polarity, low profile planar antenna for receiving high definition television signals includes a dielectric substrate having a first side and a second side on which are respectively formed first and second conductive patterns. Each conductive pattern includes segments functioning as antenna elements which are arranged to form a first modified H-shaped pattern on the first side of the dielectric substrate, and a second modified H-shaped pattern on the second side of the dielectric substrate which is disposed substantially ninety degrees with respect to the first modified H-shaped pattern. Each of the H-shaped patterns includes an extended S-shaped segment.
