1. A method for reducing a null in electromagnetic radiation from an antenna assembly comprising:
- aligning a plurality of radiation elements in a common plane, the plurality of radiation elements being uniformly spaced with respect to each other semi-circumferentially about an axis perpendicular to the common plane extending centrally through a diameter line of a semi-circle formed on the common plane by the radiating elements;
forming a first reflector to have an inverted, truncated, semi-circular conical configuration;
positioning a first reflector centrally with respect to the diameter line of the semi-circle formed on the common plane by the radiation elements;
spacing a first base of the first reflector in proximity to the radiating elements, a second base of the first reflector being disposed further away from the radiation elements than the first base, wherein the second base of the first reflector has a diameter that exceeds a footprint of the radiating elements; and
reflecting electromagnetic radiation emitted by the radiation elements along the axis and through the common plane by the first reflector to provide a coverage area that extends along the axis beyond the antenna assembly.

Abstract
Exemplary embodiments, the present disclosure are related to an antenna system including radiating elements and reflectors. The reflectors can be disposed with respect to the radiating elements to reflect radiation from the radiating elements to generate a coverage area that exceeds the coverage area generated by the radiating elements without the reflectors.
