1. An antenna system, comprising:
a plurality of chips; and
a beam forming phased array that comprises a plurality of radiating waveguide antenna cells,
wherein each radiating waveguide antenna cell comprises a plurality of pins that are connected to ground,
wherein a body of the each radiating waveguide antenna cell corresponds to the ground, and
wherein the plurality of chips are electrically connected with the plurality of pins and the ground of each of the plurality of radiating waveguide antenna cells to control beamforming through a second end of the plurality of radiating waveguide antenna cells.
