  • Metamaterial-based variable capacitor structure
    Patent number: 11764449
    Abstract: The present invention discloses a metamaterial-based variable capacitor structure, comprising the first substrate, the second substrate, the metamaterial dielectric layer, the metal floor layer between the first substrate and the metamaterial dielectric layer, the gaps and isolation holes periodically arranged on metal floor layer, the microstrip line between the second substrate and the metamaterial dielectric layer, the periodically loaded branches, the bias line and the choke branch on the microstrip line, and two feeding terminals on both ends of microstrip line. The capacitance value of the metamaterial-based capacitor with variable dielectric constant is adjusted by controlling the voltage applied to the said bias line, thereby realizing the time-frequency response, frequency selection, phase shift control, transmission matching, etc. based on the variable capacitor structure.
