Claim 0:
1. A beam steering vehicle radar for object identification, comprising:
a radar module comprising at least one beam steering transmit antenna configured to radiate one or more radio frequency (“RF”) beams in a plurality of directions, at least one beam steering receive antenna configured to receive one or more RF return signals, and a transceiver configured to generate radar data capturing a surrounding environment of an object from the one or more received RF return signals; and
a perception module configured to detect and identify the object in the surrounding environment from the radar data,
wherein the at least one beam steering transmit antenna is coupled to the transceiver by a transmission line,
wherein the transmission line is disposed on a first surface of the substrate and electrically coupled to a ground layer disposed on a second surface of the substrate, the transmission line comprising a side lobe reduction mechanism formed within a thickness of the substrate that reduces side lobes in the radiated one or more RF beams, and
wherein the side lobe reduction mechanism comprises a conductive contact formed within the substrate, is configured to conductively couple the transmission line to the ground layer, and is positioned at a terminal end of the transmission line.
