Research of Nematic Liquid Crystal Broadband tunable power divider

Basing on split-ring resonator(SRR), a compact broadband power divider has been implemented. The power divider uses common inverted microstrip line, and loads DSRRs unit on microstrip line metal conduction band, and at the same time loads nematic liquid crystal on inverted microstrip lines. Using Nematic Liquid Crystal in external bias with permittivity of dielectric constant variable attributes, a c-band broadband power divider is designed. The power divider not only has the advantage of compact size, low loss and easy fabrication, but the advantage of easy integration with other circuits.
