LOW-TEMPERATURE CO-FIRED CERAMIC SUBSTRATE STRUCTURE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a low-temperature co-fired ceramic substrate structure suitable for formation of an antenna element and the like.

SOLUTION: In a low-temperature co-fired ceramic substrate structure 1, a plurality of sheet layers S1-S8 having conductor layers C1-C8 provided in dielectric layers I1-I8 are stacked and burnt. A ground electrode 2 is formed in the conductor layer C8 of the sheet layer S8 positioned on a back side 1a. Between the ground electrode 2 and a radiation electrode 4 of the conductor layer C1 of the sheet layer S1 positioned on a front side 1b, a cavity part 3 is provided in a predetermined location in the predetermined sheet layers S3-S6 positioned between the sheet layer S8 and the sheet layer S1.
