✦ Synopsis

The design of CPW bandpass filters with electromagnetic simulations dri¨en indirectly by an equal ripple based optimizer is presented. This ¨ector procedure has se¨eral ad¨antages o¨er the general-purpose optimization routines pre¨iously 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 y3.5
