Abstract

An antenna system includes a first substrate, a plurality of chips and a waveguide antenna element based beam forming phased array that includes a plurality of radiating waveguide antenna cells for millimeter wave communication. Each radiating waveguide antenna cell includes a plurality of pins where a first pin is connected with a body of a corresponding radiating waveguide antenna cell and the body corresponds to ground for the pins. The first pin includes a first and a second current path, the first current path being longer than the second current path. A first end of the radiating waveguide antenna cells is mounted on the first substrate, where 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 for the communication.
