Single-Wall Carbon Nanotube-based Flexible Monopole Antenna Fabricated using Poly (methyl methacrylate)-supported Transfer Technique

Abstract

The demand for flexible antennas is growing due to the increasing number of IoT -related devices. We fabricated single-wall carbon nanotube (SWCNT)-based flexible monopole antennas using our developed poly (methyl methacrylate)-supported transfer technique. We evaluated reflection coefficients $(\vert S_{11}\vert)$, radiation patterns, and maximum gain of the un-bended and bended SWCNT antennas. The maximum gains of the unbended and bended SWCNT antennas were almost the same, and the radiation patterns behaved similarly to a metal antenna. These results demonstrate versatile potential for the application of SWCNT films to flexible antennas.
