Millimeter-Wave Display-Mounted Antenna for Hand Gesture Sensing on Mobile devices

Abstract

In this paper, we propose a millimeter-wave (mmWave) printed-type antenna that can be mounted on display panel of mobile devices for hand gesture sensing. To be mounted on a narrow dead-zone in the display, the antenna has a thin strip. The antenna resonates between the adjacent strip and the ground slot, and it has a fractional impedance bandwidth of 12.3%. The simulated and measured results show that the proposed antenna can be utilized for hand gesture sensing by interfacing the antenna with a mmWave commercial radar module.
