Abstract
This document describes a waveguide with radiation slots and parasitic elements for asymmetrical coverage. An apparatus may include a waveguide for providing asymmetrical coverage in an azimuth plane. The waveguide includes a hollow channel containing a dielectric and an array of radiation slots through a surface that is operably connected with the dielectric. The waveguide includes an array of parasitic elements positioned on or in the surface and offset from a longitudinal side of the array of radiation slots. The radiation slots and parasitic elements configure the described waveguide to focus an antenna radiation pattern that provides an asymmetrical coverage to focus on a particular portion within the antenna field-of-view.
