| Abstract: | The general method of analyzing microtril5 filters is full-wave electromagnetic method, but the calculation and programming of this method are so complex that it is very inconvenient to use. A simple and precise method named impedance analysis method is proposed to analyze the transmission characteristics of microtrip filters faster and more efficiently, which is of great significance for probing into simple and fast methods to design novel filters with small mass, light weight and good performance, The continuous varying bandstop and lowpass microtrip filters are analyzed and designed by the impedance analysis method,shapes and structural measures are given as well. Several typical kinds of microtrip filters are made experimentally and the tested results and consist ent with the theoretical results. |
