1. An apparatus comprising:
a waveguide channel that includes a hollow channel for a dielectric, the hollow channel including a plurality of slot antennas, each of the slot antennas comprising an opening through a surface of the waveguide channel that defines the hollow channel, each of the slot antennas being operably connected with the dielectric; and
two reflectors positioned adjacent to and offset from each longitudinal side of the waveguide channel, the reflectors and the waveguide channel being arranged to produce a particular radiation pattern for an antenna element that is electrically coupled to the dielectric, wherein:
a first reflector of the two reflectors is offset a first distance from a first longitudinal side of the waveguide channel, and
a second reflector of the two reflectors is offset a second distance from a second longitudinal side of the waveguide channel, the second distance not being equal to the first distance.
