The miniaturized radar sensor for detecting short distances is realized using a six‐port network. The six‐port network of the radar sensor consists of passive components and RF power detectors. The power detector obtains a highly accurate DC voltage because DC offsets are cancelled using a dummy structure in the detector. The maximum error of a distance measurement to 3 m is approximately 2% for a single target. Using traveling wave antennas, the distances to two targets with different directions are measured with 6.7% maximum detection error to 1 m. © 2014 Wiley Periodicals, Inc.
