Compact Bendable Multiwalled Carbon Nanotube/PDMS Antenna for WLAN and Wi‐Fi 6E Wearables in 5G/6G Networks

This article presents a compact, simplified structured, bendable, and lightweight antenna for wearable electronic devices. A multiwalled carbon nanotube and polydimethylsiloxane composite material is utilized for the radiating patch and ground plane, while curved PDMS is used as a substrate material. The design consists of a rectangular‐shaped patch loaded with rectangular‐shaped stubs to improve the impedance bandwidth and matching of the proposed antenna. The comparative simulated and experimental results indicate that the obtained antenna design is flexible and has good dielectric properties. The proposed antenna offers dual bands at 5.19–5.6 and 6.68–6.92 GHz, which cover wireless local area network and Wi‐Fi 6E frequency bands. The conformal analysis of the proposed antenna is performed, which offers stable outcomes in terms of S‐parameter, gain (>4.5 dBi) and radiation efficiency (>87%). Moreover, the design is also placed on the human body phantom to study the specific absorption ratio analysis and gain of the antenna. The results obtained from the proposed antenna, along with comparisons to recent work, demonstrate its strong performance and suitability for integration into wearable electronic devices operating within the 5G and 6G frequency bands.
