Abstract

In this paper, an X-band negative resistance oscillator based on the active substrate integrated waveguide (ASIW) is proposed. The ASIW is connected to the series feedback circuit to compensate the electromagnetic energy consumed by the resonator. This method is an effective way to improve the quality factor of the resonator and to suppress the phase noise of the oscillator. The proposed oscillator is measured by the spectrum analyzer with excellent performance and it can be applied in the modern wireless communication networks and systems.
