1. An apparatus, the apparatus comprising:
a folded waveguide comprising a hollow core for air, the hollow core forming a sinusoidal shape that folds back and forth about a longitudinal axis that runs in a longitudinal direction through the hollow core; and
a plurality of radiation slots, each of the radiation slots comprising a hole through one of multiple surfaces of the folded waveguide that defines the hollow core, the plurality of radiation slots being arranged on the one of the multiple surfaces to produce a particular antenna pattern at an antenna element that is electrically coupled to the air in the hollow core.
