Abstract In this article, we have obtained simple excess capacitance formula for asymmetric stripline open‐end. The average error of the formula is less than 2%. On the basis of this formula and the field‐based equivalent circuit model obtained by the authors before, a low‐pass filter and an edge coupled stripline band‐pass filter are analyzed by the field‐based equivalent circuit together with the excess capacitance formula of this article. Compared with numerical results, the average errors of S parameters are less than 2%. © 2008 Wiley Periodicals, Inc.
