Abstract :
Miniaturization of microwave devices poses challenges, as there are a lot of electromagnetic phenomena to be considered in its development. Increasing the electric permittivity of ceramics used in filters goes towards miniaturization, but traditional feeding techniques are not good enough to provide a good frequency response. This work shows modifications needed to feed filters build with ceramics of high electric permittivity.
