The design of CPW bandpass filters with electromagnetic simulations driven indirectly by an equal ripple based optimizer is presented. This vector procedure has several advantages over the general‐purpose optimization routines previously applied to the design of CPW filters. The filter, which employs three resonators with a combination of both edge and end coupling, has a center frequency of 23 GHz with a 1.8‐GHz bandwidth and a measured insertion loss of only −3.5 dB. © 1997 John Wiley & Sons, Inc.
