    Abstract: A semiconductor device includes: a dielectric substrate; an integrated circuit (IC) die disposed inside an opening of the dielectric substrate, where the IC die is configured to transmit or receive radio frequency (RF) signals; a dielectric material in the opening of the dielectric substrate and around the IC die; a redistribution structure along a first side of the dielectric substrate, where a first conductive feature of the redistribution structure is electrically coupled to the IC die; a second conductive feature along a second side of the dielectric substrate opposing the first side; a via extending through the dielectric substrate, where the via electrically couples the first conductive feature and the second conductive feature; and an antenna at the second side of the dielectric substrate, where the second conductive feature is electrically or electromagnetically coupled to the antenna.

    Abstract: A method of forming a radar system includes 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, 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 chip to the radar package. The radio frequency integrated circuit chip is coupled to the transmit antenna, the first receive antenna, and the second receive antenna. The second surface is opposite the first surface.

    Abstract: A radar system includes a substrate that includes a first surface and a second surface. The first surface is opposite the second surface. The radar system further includes transmitter front-end circuitry attached to the substrate and configured to transmit a transmitted radio frequency (RF) signal in a first direction away from the first surface and in a second direction away from the second surface. The radar system also includes a first receive antenna and a second receive antenna. The first receive antenna is disposed at the first surface and is configured to receive a first reflected RF signal propagating in the second direction and generated by the transmitted RF signal. The second receive antenna is disposed at the second surface and is configured to receive a second reflect RF signal propagating in the first direction and generated by the transmitted RF signal.

    Abstract: A device includes: a millimeter-wave radar sensor circuit configured to generate N virtual channels of sensed data, where N is an integer number greater than one; and a processor configured to: generate a 2D radar image of a surface in a field of view of the millimeter-wave radar sensor circuit based on sensed data from the N virtual channels of sensed data, where the 2D radar image includes azimuth and range information, generate a multi-dimensional data structure based on the 2D radar image using a transform function, compare the multi-dimensional data structure with a reference multi-dimensional data structure, and determine whether liquid is present in the field of view of the millimeter-wave radar sensor circuit based on comparing the multi-dimensional data structure with the reference multi-dimensional data structure.
