In this article, Microwave oscillator was designed, fabricated, and characterized using the folded T‐type slot resonator for X‐band applications. The miniaturized resonator was designed by terminating the slot lines at both ends of the T‐structure. The simulation and experimental results were compared and found a closed agreement between them. The oscillator using the folded T‐type slot resonator showed phase noise performances of −105.54 dBc/Hz at a 100 kHz offset from the carrier frequency of 8.5 GHz with an output power of 14.06 dBm. The oscillator exhibited better phase noise characteristic due to the high unloaded Q value of the folded T‐type slot resonator, which is considerably higher than that of miniaturized spurline resonators. The figure of merit of the oscillator achieved a −183.34 dBc/Hz. The feasibility of integrating that slot resonator in various monolithic microwave integrated circuit technologies can also be expected. © 2012 Wiley Periodicals, Inc.
