Abstract A stripline T‐resonator is designed and implemented in the LTCC substrate for millimeter wave applications. The loss‐free air cavities are embedded at both side edges of the conducting strip in order to efficiently reduce the dielectric loss of the stripline structure. The resonator was implemented using 4‐layer LTCC dielectrics. The fabricated stripline resonator with air cavities reveals Q‐factor of 248 and total loss of 0.035 dB/mm at 34.7 GHz, and that is improved by 108% and 51%, respectively, compared to the conventional one. The proposed LTCC stripline resonator with the embedded air cavities can meet demands for low‐loss millimeter‐wave system‐on‐package (SoP) applications. © 2008 Wiley Periodicals, Inc.
