Mingyu Nie, Dingfei Ma, Qingfeng Zhang · IEEE Antennas and Wireless Propagation Letters · 2024
This article presents a novel 2-D near-field sensing system based on a single-port multimode resonant antenna and convolutional neural network (CNN) algorithms. The proposed system utilizes frequency diversity scheme to detect perturbations within the 2-D aperture in a single shot. Leveraging the benefits of multiple cavity modes, the proposed sensing system features enhanced sensing capacity. The multimode resonant antenna is designed based on a substrate integrated waveguide resonator etched with complementary split-ring slots. Experimental results demonstrate the effectiveness of the proposed system in accurately classifying various hand gestures using the CNN framework.
