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.
