SUMMARY
The forum discussion centers on enhancing the coupling of coaxial cables to a resonator designed to produce whispering gallery modes at frequencies of 9.87 GHz and 11.29 GHz. Participants suggest that better coupling may involve modifying the probe dimensions and configuration, specifically by removing the shield and connecting the probe tip directly to the cavity wall to create a loop antenna. This approach can improve coupling by utilizing magnetic fields, which may induce higher currents in the cavity walls, although it may also reduce the quality factor (Q) of the cavity.
