Microstrip line is characterized by many advantages such as easy fabrication, compact size, lightweight, planar structure, and easy integration with other components on a single circuit board. In this article, a novel microstrip millimeter wave band‐pass filter with slow‐wave resonator is presented. By introducing cross‐coupling capacitance between the input and output ports of the filter, a slow‐wave resonator is suggested to improve both selectivity and stopband rejection. The proposed microstrip filter also has the merits of compact size and high stopband rejection. The experimental results on a fabricated filter agree with the simulated results very well. It might be widely used in plane circuits and advanced circuits such as MMIC and LTCC. © 2008 Wiley Periodicals, Inc.
