Claim 15:
16. A beam steering vehicle radar for object identification, comprising:
at least one beam steering receive antenna having a plurality of antenna elements configured to receive one or more RF return signals, comprising:
a substrate;
a ground layer disposed on a first surface the substrate;
a conductive transmission line disposed on a second surface of the substrate opposite the first surface, the conductive transmission line comprising a plurality of patches forming an antenna element in the plurality of antenna elements; and
a side lobe reduction mechanism formed within the substrate configured to conductively couple the conductive transmission line to the ground layer, wherein the side lobe reduction mechanism is formed within the substrate in a cross-sectional view and positioned at a terminal end of the conductive transmission line; and

a perception module configured to detect and identify an object in a surrounding environment of the object from radar data generated from the one or more RF return signals.
