Abstract
For example, an apparatus may include a radar antenna including at least one Transmit (Tx) antenna to transmit a Tx radar signal; and a plurality of Receive (Rx) antennas to receive Rx radar signals based on the Tx radar signal, wherein a distance between a first Rx antenna of the planarity of Rx antennas and a second Rx antenna of the plurality of Rx antennas, which is adjacent to the first Rx antenna, is at least ten times a wavelength of a central frequency of the Tx radar signal.
