This document describes techniques, apparatuses, and systems for a waveguide with lobe suppression. A waveguide is described that includes a pipe for containing a dielectric, the pipe defining an open end to a longitudinal direction through the pipe. An array of radiating slots is formed through a surface of the pipe and in communication with the dielectric. To suppress grating lobes in an antenna pattern, the waveguide includes at least one parasitic groove that is separate from the pipe and with at least a portion of a length that is parallel to the array of radiating slots. In this way, the waveguide provides an antenna pattern where grating lobes are suppressed or substantially reduced.
