Resonant EBG-based common mode filter for LTCC substrates

To develop usable EBG-based common mode fliters miniaturization is required. In this paper is introduced a quarter-wavelength resonant EBG-based common mode filter on LTCC substrate whose dimensions are miniaturized according a systematic stepped procedure. Results in terms of common mode attenuation and differential mode transmission are presented. Consideration is also given to the decreasing of the direct radiation.
