Abstract :
This letter describes the design and performance characteristics of a new monolithic Ka-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 TE01delta 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
