In this study, different coupling methods for a
cylindrical dielectric resonator operating in TE01δ mode
were investigated and compared at 14T. The best coupling
method was selected based on the analysis of the
scattering parameters. It yielded a Q-factor around
716.2 and S21 value of -9.20 dB. The relationship
between different Q-factors and their effects on S21
were discussed. The results from this study will be
useful for the new designs on MRI probe head made of
cylindrical dielectric resonators.
