Abstract

Novel design opportunities for microstrip bandpass filters built by using layered substrates of mixed ceramic dielectrics having different permittivities are investigated on the example of a filter for UHF band. The possibilities to enhance and control the rejection band characteristics are demonstrated based on FDTD simulations and lumped element equivalent circuits. A miniature LTCC-filter of (3.6times2.8) mm² size is presented. Measurements of the filter prototypes fabricated by using the multilayer LTCC technology have confirmed the design principles with good agreement.
