Abstract

We present a low pass stepped impedance filter which is based on a single microstrip line of uniform width. The impedance of the line is influenced by the region of the substrate on which the filter section is disposed. A large high-to-low impedance ratio is achieved by application of the Maxwell-Wagner polarization mechanism which results into a colossal effective electric permittivity. This method is competitive to other implementations as it is fully compatible with standard CMOS technologies, exhibits a large attenuation factor in the stop band and results into a compact design.
