Abstract: We present a simple compact meander spurline resonator and its application to low phase noise oscillator. The resonator which has a bandstop characteristic is used in the series feedback of oscillator. This miniaturized resonator consists of a defected meander spurline with inductive characteristics and capacitive characteristics. The microwave oscillator using the meander spurline resonator shows excellent phase noise performances of -103.23 dBc/Hz at a 100 kHz offset from the carrier frequency of 9.0 GHz with an output power of 15.23 dBm due to the high Q value of the defected meander spurline resonator. The structure of resonators reduces the size and the cost.
