In this article, the X‐band low‐phase noise oscillator based on a μ‐near zero (MNZ) metamaterial resonator is presented. The MNZ resonator has small size and high loaded quality factor (Q L ) and the oscillator has low‐phase noise due to high‐Q L . Also, the proposed resonator is composed of complimentary structure which consists of spur‐line and meander‐line. The measured Q L of a new resonator is 213 at resonant frequency of 10 GHz and the output power and second harmonics suppression are 14.43 dBm and −30.65 dBc, respectively. The measurement result for phase noise is −101.71 dBc/Hz at 100 kHz offset.
