Abstract

In this paper, the variational method are used for the filter analysis methods and a CAD program for the design of the waveguide low-loss bandpass filters using inductive window structures for the VSAT(Very Small Aperture Terminal) system has been developed based on the passband correction method combined with fiter synthesis procedures. Using the developed CAD program, 0.01dB equi-ripple chebyshev type 6-section bandpass filters which are sued in the VSAT system operating nationally are designed for the purpose of the Down-link of 12.75~13.25GHz and the Up-link of 14.0~14.5GHz, fabricated and mesured. The measured results are good agreement woth the theoretical resuls.
