Abstract： This paper studies a design method of compact multi-band microstrip line filter. The filter adopts a design method based on impedance conversion theory. By properly selecting the width and spacing of microstrip lines, and the layout of impedance conversion elements, multiple frequency bands can be realized in a compact microstrip line structure. Through simulation and experimentation, the effectiveness and feasibility of the design method of the filter are proved.
