Abstract: This document describes techniques, apparatuses, and systems for a waveguide with slot antennas and reflectors. An apparatus may include a waveguide channel that includes a hollow channel containing a dielectric and an array of slot antennas through a surface that is operably connected with the dielectric. The apparatus also includes reflectors positioned adjacent to and offset from each longitudinal side of the waveguide channel. The reflectors and the waveguide channel are positioned to generate a particular radiation pattern for an antenna element electrically coupled to the dielectric. In this way, the described waveguide with slot antennas and reflectors can adjust the positioning of the reflectors to provide a radiation pattern with a wide or asymmetric beamwidth.
