Abstract
An approximately planar wideband antenna can include a first conductive portion coupled to a dielectric portion and mechanically supported by the dielectric portion, the first conductive portion including at least one edge corresponding to a planar conic section, such as including one or more of an elliptic, a parabolic, or a hyperbolic shape. Such an antenna can be electrically coupled to a matching circuit, the matching circuit configured provide a specified input impedance corresponding to a specified range of frequencies. Such a range of frequencies can span at least an octave, or more.
