Claim 8:
9. A radio unit comprising:
one or more antenna modules configured to emit or receive mmWave radio signals; and
a dielectric waveguide body comprising:
an upper surface disposed in relation to the one or more antenna modules such that the mmWave radio signals emitted or received by the one or more antenna modules pass through the dielectric waveguide body;
a perimeter surface; and
an internal reflection surface disposed opposite the upper surface and having a quasi-parabolic shape configured to redirect mmWave radio signals propagating through the dielectric waveguide from the upper surface to form a main beam and one or more sidelobes, the main beam being emitted from the dielectric waveguide body through the perimeter surface;

wherein the one or more antenna modules comprise a plurality of antenna modules of a planar array antenna; and
wherein a first set of antenna modules is positioned proximal a focus of the internal reflection surface, the first set comprising one or more of the plurality of antenna modules.
