A method to realize ultra-low temperature co-fireable ceramic composites with ultra-low permittivity is presented in this work. Hollow glass microspheres with a size of 10–100 μm were used as a filler in a tape based on lithium molybdate (Li2MoO4)

Low Temperature Co-fired Ceramic (LTCC) is one of the cornerstones of today׳s multilayer electronics. However, the relatively high permittivity of LTCC materials limits their usage at high frequencies. In order to expand the applications of LTCC a m
