Abstract :
We have implemented a novel high-Q low temperature co-fired ceramic (LTCC) stripline resonator by including air cavities in the LTCC substrate for millimeter-wave applications. This new resonator presents Q-factor of 290 and total loss of 0.03 dB/mm at 34.8 GHz, and they are improved by 138% and 58%, respectively, compared to the conventional one. Its dielectric loss is analyzed as small as 0.0003 dB/mm at the resonant frequency, and that improved by a factor of 120 compared to the conventional one.
