A Monolithic Differential Coupling Mechanism for Dielectric Resonators Excitation in Conductive Silicon Substrates

This letter describes the design and performance characteristics of a new monolithic K
_a
-band differential printed dipole launcher that is used to excite a dielectric resonator (DR) in the presence of a conducting silicon substrate. The configuration was fabricated using the IBM SiGeHP5 process and was experimentally tested. Good agreement is obtained between the simulations and experimental results for the TE
_01delta
mode of cylindrical DRs. The developed excitation mechanism can be used with fully integrated differential DR oscillators or on-chip DR antennas implemented using silicon-based technology
