Abstract

An antenna system, includes a first substrate, a plurality of chips, and a waveguide antenna element based beam forming phased array. The waveguide antenna element based beam forming phased array has a unitary body that comprises a plurality of radiating waveguide antenna cells in a first layout for millimeter wave communication. Each radiating waveguide antenna cell comprises a plurality of pins that are connected with a body of a corresponding radiating waveguide antenna cell that acts as ground for the plurality of pins. A first end of the plurality of radiating waveguide antenna cells of the waveguide antenna element based beam forming phased array, as the unitary body, in the first layout is mounted on the first substrate. 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.
