Abstract
The invention is directed to an antenna array comprised of conical helical antennas with at least one of the antennas being a tilted conical helical antenna. In one embodiment, a tilted conical helical antenna in the array comprises an electrically conductive wire that follows a helical path on a frustum of an oblique elliptical cone in which the axis of the cone is tilted relative to the planar base surface of the cone (i.e., not perpendicular or parallel to the surface) in a plane defined by the axis and a phase center axis of the array. Each of the tilted conical helical antennas in an array is spaced from the phase center axis of the array. The degree of tilt increases the farther an antenna is located from phase center axis.
