Claim:
1. An antenna array, which comprises: a plurality of antenna elements, the plurality of antenna elements being configured in a flare such that each of the plurality of antenna elements is uniformly spaced apart from at least one adjacent antenna element based on wavelengths associated with an operating frequency band, thereby providing a constant beamwidth over the operating frequency band, each of the plurality of antenna elements being coupled in a common area, each of the plurality of antenna elements extending radially outward from the common area; and an axis of symmetry extending through the common area, at least one of the plurality of antenna elements comprising a planar area, the planar area comprising an edge, the edge being disposed non-parallel to the axis of symmetry when viewed in a direction that is normal to the axis of symmetry and coplanar with the planar area.
