Patent ID: 7791555

Claim:
An antenna assembly for receiving and transmitting radio frequency signals in a range around a characteristic wavelength comprising: a first radiative element, having a first end and a second end and comprised of an electrically conductive material, the first end of the first radiative element electrically connected to an antenna feed at an apex point and at least a portion of the first radiative element being disposed outwardly away from the apex point at an acute angle relative to, and on a first side of, an imaginary plane intersecting the apex point; a second radiative element, having a first end and a second end and comprised of an electrically conductive material, the first end of the second radiative element electrically connected to the antenna feed and the first radiative element at the apex point, at least a portion of the second radiative element extending in a direction substantially perpendicular to the imaginary plane, the second radiative element comprising: a first linear segment extending upward from a first end at the apex point as to be substantially perpendicular to the imaginary plane; a plurality of curvilinear segments extending from a second end of the first linear segment, each the first plurality of curvilinear segments having a first end connected to the second end of the first linear segment and extending away from the second end of the first linear segment in a direction substantially parallel to the imaginary plane; and a polygonal element connecting respective second ends of the plurality of curvilinear segments as to form a closed shape; and an electrically conductive ground reference.
