Smart wearable electronic demands thin and flexible radio-frequency (RF) antennas for wireless communication system. Previously, different nanostructured materials and metals have been used for RF antenna depends on their electrical conductivity. Metal-based antennas are thick and bulky due to their theoretical skin depth issue, which restrict miniaturized and portable electronics. Firstly, we report metallic two-dimensional (2D) metal chalcogenide-based monopole patch RF antenna, which is operated even at much lower thickness (sub-micron) than the skin depths of metals and omnidirectional RF propagation with reconfigurable resonance frequency. This work opens new approaches to design RF antennas for body-centric wearable communication systems. |
