This article proposed a new high‐Q L resonator with a combination of a double spiral resonator and single split ring resonator with μ‐ near zero metamaterial.It is applied to the design of an X‐band oscillator. A very low phase noise for the oscillator can be obtained due to its sharp band‐ rejection characteristic of the new resonator. The oscillator is designed to operate at 9.2 GHz using the new resonator. Experimental results show the output power is 14.13 dBm, the second harmonic suppression is −46.33 dBc, and the phase noise is −104.54 dBc/Hz at 100‐kHz offset. © 2012 Wiley Periodicals, Inc.
