Claim 6:
7. 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 receive antenna comprises a substrate comprising a conductive transmission line disposed on a first surface of the substrate, a ground layer disposed on a second surface opposite the first surface, and a side lobe reduction mechanism electrically coupling the conductive transmission line to the ground layer through a thickness of the substrate, and
wherein the side lobe reduction mechanism is configured to reduce side lobes in the one or more RF return signals.
