A low phase noise oscillator with a high-Q split ring resonator using MNG metamaterial
Abstract
In this article, a novel high QL triple-split ring resonator (T-SRR) of mu-negative metamaterial is suggested.It is used in the design of an I- band oscillator. A very low phase noise can be obtained for the oscillator due to the sharp band-rejection characteristic of T-SRR. The oscillator is designed to operate at 10 GHz using the novel T-SRR. Experiments show that the output power is 9.82 dBm, the second harmonic suppression is −26.48 dBc, and the phase noise is −105.05 dBc/Hz at a 100-kHz offset. © 2011 Wiley Periodicals, Inc.
