1. A method of forming a radar system, the method comprising:
forming a first receive antenna and a first ground plane region by patterning a first conductive layer on a first surface of a first laminate layer of a radar package;
forming a transmit antenna and a second ground plane region by patterning a second conductive layer on a second surface of the first laminate layer, the second surface being opposite the first surface;
forming a second laminate layer of the radar package over the second conductive layer;
forming a third conductive layer over the second laminate layer;
forming a second receive antenna by patterning the third conductive layer; and
attaching a radio frequency integrated circuit (RFIC) chip to the radar package, the RFIC being coupled to the transmit antenna, the first receive antenna, and the second receive antenna.
