First generation of ultrathin Polarized NanoMaterials for millimeter-wave (26–40 GHz) textile antenna applications

A novel PNM textile with extremely small thickness on the order of a few micron was characterized at millimeter wave frequencies (26.5 – 40 GHz), and the impedance analysis of the material was presented. The results show that the PNM is an excellent absorber for wideband applications; the highly polarized materials can be utilized for polarization detection and sensing applications. The impedance results of the PNM textile show that CNTs can function as resonators at microwave frequencies due to the long nanotubes, hence, paving ways for further theoretical and experimental studies on these behaviors. In future research efforts, the PNM will be characterized in gas to establish a foundation for wireless gas sensor designs in the microwave frequency range.
