Demonstration of MIMO High-Scanning-Rate Coupled-Resonator Antennas for 2-D Multitarget Localization and Heartbeat Rate Monitoring

This paper proposes a multi-input multi-output (MIMO) high-scanning-rate coupled-resonator antennas at millimeter-wave frequency band for 2-D multi-target localization and heartbeat rate monitoring. The designed coupled-resonator antenna is able to vertically scan beam across a 47<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> angular range as frequency changes from 60GHz to 64GHz, while 3Tx×4Rx MIMO technology can achieve digital beam scann
