VOLTAGE CONTROLLED OSCILLATOR USING VARACTOR-LOADED SPLIT-RING RESONATOR

摘要

A voltage controlled oscillator using a VLSRR(Varactor-Loaded Split-Ring Resonator) is provided to obtain a very thin thickness by etching a metal on a substrate. A split ring resonator(101) is comprised of an inner ring and an outer ring. A microstrip transmission line(111) is separated from the split ring resonator with a predetermined interval. Both ends of a varactor diode(102) are connected to the inner ring and the outer ring of the split ring resonator. An amplifier is connected on the microstrip line and generates the oscillation signal. The oscillation frequency of the amplifier is controlled according to both ends of the varactor diode. In the varactor diode, one end connected to the inner ring of the spit ring resonator is grounded. The other end connected to the outer ring is connected to the power supply unit.
