A review on quality factor enhanced on-chip microwave planar resonators
Engineering Science and Technology, an International Journal, 2017 This paper reviews microwave on-chip resonators with emphasis on quality-factor (Q-factor), and techniques enhancing Q-factor. The review discusses both planar microstrip and waveguide structures, with the integration of the latter emerging as a ...

Optimization and Design of Wideband Antenna Based on Q Factor
International Journal of Antennas and Propagation, 2015 A wideband antenna is designed based on Q factor in this paper. Firstly, the volume-surface integral equations (VSIEs) and self-adaptive differential evolution algorithm (DEA) are introduced as the basic theories to optimize antennas.
