Abstract: Provided herein are various enhancements for radio frequency antennas and antenna arrangements. In one example, an apparatus comprises a reflector for radio frequency energy having a reflector surface comprising a paraboloid of revolution that establishes an inverted truncated conical shape with a concave nappe. The reflector surface is configured to interact with the radio frequency energy to direct at least a portion of the radio frequency energy towards a feed array mounted about a perimeter of the inverted truncated conical shape.
