Abstract
Recent developments in wearable wireless communication systems have significantly increased the demand for stretchable antennas. The substrate, which is a critical component for antennas, has a great impact on the antenna’s electromagnetic performance and mechanical properties, particularly at millimeter-wave frequencies. However, conventional methods of incorporating low-loss ceramics into stretchable polymers cannot achieve an equilibrium between low dielectric loss and optimal stretchability. To resolve this issue, we present a novel approach that synergistically integrates electrospun barium titanate (BaTiO3) nanofibers with poly(dimethylsiloxane) (PDMS), achieving a composite membrane substrate with ultralow dielectric loss and exceptional stretchability. Based on this advanced substrate, we develop a wearable array antenna that demonstrates stretchability and remarkable radiation characteristics, effectively addressing the constraints associated with conventional PDMS-based antennas. This proposed antenna is expected to be an excellent candidate for next-generation wearable and stretchable millimeter-wave 5G wireless communication.
期刊介绍:
ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
