Classification: CPC H | IPC H

Claim 0:
1. A dielectric waveguide body comprising:
an upper surface configured to receive mmWave radio signals emitted by one or more antenna modules of a radio unit;
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 within the waveguide body from the upper surface to generate a main beam and at least one sidelobe, the main beam being emitted from the dielectric waveguide body through the perimeter surface;
the internal reflection surface having a focus, and wherein radio signals emitted by an antenna module located proximal the focus are redirected to generate the main beam.
