We show how a high‐dispersion composite right/left‐handed metamaterial leaky wave antenna can be deployed as a compact sensor for localization. The antenna, unlike previous leaky wave scanning antennas, requires only a narrowband frequency stimulation range, 450 MHz for −68° to +27° scanning including broadside for 2‐GHz center frequency operation. The antenna is equipped with a detector diode so that homodyne detection of objects in its field of view can be obtained. As the antenna is frequency scanning, spatial location information is additionally presented to the detector. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1883–1886, 2014
