Radar sensors in the millimeter wave range usually consist of an antenna system, a radar circuit, a digital processor for signal evaluation and a power supply. The radar circuit is monolithically integrated and is referred to as MMIC. The antenna system used is either an array consisting of many individual antennas, as described in Chap. 6, or a single antenna, which is often designed as a primary radiator together with beamforming lenses. This chapter focuses on the two components MMIC and antenna, as the processing unit and power supply are usually available as standard components.
