Abstract: PURPOSE: A VCO(Voltage Controlled Oscillator) is provided to decrease a phase noise by including a high quality coefficient. CONSTITUTION: A VCO(100) includes an energy compensation IC(110) and a split ring resonation PCB(120). In the split ring resonation PCB, a split ring resonator having meta material characteristics is installed on a PCB. In the energy compensation IC, a circuit to generate resonance from the split ring resonator is formed with the form of an IC. The split ring resonator has a negative refractive index and negative magnetic permeability. [Reference numerals] (110) Energy compensation IC; (120) Split ring resonation PCB

Abstract: PURPOSE: A low phase voltage control oscillator using a split ring resonator structure of a meta material is provided to improve phase noise characteristics through the improvement of a Q value using a unit cell of a SRR(Split Ring Resonator) structure. CONSTITUTION: A resonant portion includes a unit cell(210) of a SRR structure. A coupling capacitance value increases using the SRR structure having a property of a LHM(left handed material). The unit cell of the SRR structure comprises a first unit signal line(211), a second unit signal line(212), a third unit signal line(213), and a fourth unit signal line(214). The first unit signal line has an open slit portion(211a) formed on one end portion and an enclosed slit portion(211b) formed on the other one portion.
