A novel Metamaterial resonator based signal source for application in current and later generation radio communication systems

Manipulating and tailoring the electromagnetic wave properties of artificial negative index material, known as Metamaterials or left-handed (LH) material foresee inspiring relevance in modern radio communication systems. In particular, this paper addresses the application of left-handed material for building high performance tunable VCO (3.9-4.2 GHz) for the applications in portable and test & measurement equipments. The reported measured phase noise @ 1MHz offset is - 151dBc/Hz @ 1MHz offset from carrier with DC operating condition of 5V and 40mA, delivering output power more than 3dBm over the operating frequency band.
