  • Ultrawideband antenna
    Patent number: 7327315
    Abstract: Antennas for transmitting and receiving ultrawideband (UWB) signals are disclosed. A UWB antenna structure includes a planar conductor of substantially uniform resistance. The structure has the shape of a pair of conjoined, generally triangular figures, each with a long side, a short side, and a curved side. The triangular figures have an antenna feed connection at one corner. The structure has an axis of symmetry passing through the antenna feed connection.
