Abstract :
This paper examines millimeter wave LTCC waveguide resonators and proposes a design strategy for obtaining high-Q factors using a number of loss-reduction and feeding techniques. The modeling and simulation methodology employed has been confirmed through a baseline LTCC resonator design, showing excellent agreement between measurements and predictions. An optimum design was then carried out which yielded an unloaded Q of over 1000 at Ka-band, the highest value ever reported for a standard LTCC process.
