Abstract

The microstrip square open loop resonator has been employed to reduce the phase noise in the oscillator. The square open loop resonator has a large coupling coefficient value, which makes a high Q value, and has reduced the phase noise of the oscillator. This oscillator has presented the oscillation frequency of 5.84 GHz and the phase noise of -113.17 dBc/Hz at an offset frequency of 100 kHz. The phase noise of the oscillator using microstrip square open loop resonator has been reduced -17 dBc/Hz at an offset frequency of 100 kHz compared with that of the conventional structure of the oscillator
