  • Quantitative chemical sensors with radio frequency communication
    Patent number: 11761919
    Abstract: A system for low power chemical sensing can include a voltage shift unit which receives a voltage signal from a chemical sensor unit. The voltage signal can be determined by a concentration of an analyte. The voltage shift unit can transform the voltage signal to an input voltage signal, and send the input voltage signal to a plurality of frequency selective surface (FSS) units of an FSS array. The FSS array can communicate a radio frequency (RF) signal in an Institute of Electrical and Electronics Engineers (IEEE) S band with a resonant frequency based on the input voltage to provide the concentration of the analyte.

  • Broadband monopole antenna using anisotropic metamaterial coating
    Patent number: 9837710
    Abstract: An antenna system is provided that includes an antenna having an elongated conducting segment, such as a metal rod. An anisotropic metamaterial surrounds the elongated conducting segment of the antenna. The presence of the metamaterial remarkably expands the VSWR <2. An example antenna is a monopole antenna, such as a quarter-wavelength monopole antenna, surrounded by the metamaterial.
