Abstract
A voltage-controlled oscillator (VCO), specifically, a low phase noise VCO using metamaterial transmission lines including a signal plane on which transmission lines are etched in an interdigital fashion is provided. Though high quality resonators based on a metamaterial structure, improvement of the phase noise of the VCO and circuit miniaturization are achieved.
