Improving the quality factor of the coplanar waveguide resonator

Maricar, Mohamed Ismaeel; Khalid, Ata; Cumming, David S.R.; Oxley, Christopher H. (2015)
A novel method of introducing a notch at a point of high magnetic field in a coplanar\ud waveguide (cpw) radial and diamond stub resonator to increase the quality factor (Q) was\ud analysed. For comparison both radial and diamond shaped cpw resonators with and without\ud notches were fabricated on gallium arsenide (GaAs) semi-insulating substrate at the James\ud Watt Nanofabrication Centre and tested in the milli-metric laboratory at University of\ud Glasgow. The notch increased the loaded Q factor of the diamond resonator by approximately\ud 28% and good agreement was obtained between the measured and simulated loaded Q for\ud both cpw radial and diamond resonators.
