Abstract
Aperture has been employed on the ground plane in the Hairpin resonator. Aperture made by etching the part of the ground effected coupling coefficient and then quality factor of Hairpin resonator has been increased. When the hair pin oscillator using aperture has been compared with the conventional hair pin oscillator using microstrip, it has been improved the phase noise about 19dBc @100KHz. Oscillation frequency of the hair pin oscillator using aperture has been 5.83GHz band and output power is -4.33dBm.
