D. Budimir et Id. Robertson, OPTIMIZATION-ORIENTED DESIGN OF COPLANAR WAVE-GUIDE BANDPASS-FILTERS, Microwave and optical technology letters, 15(1), 1997, pp. 52-54
The design of CPW bandpass filters with electromagnetic simulations dr
iven indirectly by an equal ripple based optimizer is presented. This
vector procedure has several advantages over the general-purpose optim
ization 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 ban
dwidth and a measured insertion loss of only -3.5 dB. (C) 1997 John Wi
