CAD of high-epsilon(r) microstrip bandpass filters
A simple design procedure is described for miniaturized microstrip bandpass filters on high-epsilon(r) substrates. Costs and design times are reduced by replacing experimental measurements with EM simulations. The procedure is confirmed through the design of a miniaturized microstrip hairpin-coupled bandpass filter at 1.8 GHz on BaO-PhO-NdzO(3)-TiO(2) (epsilon(r) = 90.9) ceramic substrate.
