Abstract
This paper presents a Doppler radar with metamaterial-based leaky-wave antennas for the hand-gesture sensing application. Since the antenna main beam of the developed radar can be arbitrarily pointed to a known azimuth angle, the hand gesture moving in the decomposed orthogonal directions can be successfully detected. In addition, the phase information caused by the hand gesture is accurately retrieved to calculate the distance of the hand movement.Keywords
