ABSTRACT
This book presents a new global optimization technique using Taguchi’s method and its applications
in electromagnetics and antenna engineering. Compared with traditional optimization techniques,
Taguchi’s optimization method is easy to implement and very efficient in reaching optimum
solutions.
Taguchi’s optimization method is developed based on the orthogonal array (OA) concept,
which offers a systematic and efficient way to select design parameters. The book illustrates the
basic implementation procedure of Taguchi’s optimization method and discusses various advanced
techniques for performance improvement. In addition, the integration of Taguchi’s optimization
method with commercial electromagnetics software is introduced in the book.
The proposed optimization method is used in various linear antenna arrays, microstrip filters,
and ultra-wideband antenna designs. Successful examples include linear antenna array with a null
controlled pattern, linear antenna array with a sector beam, linear antenna array with reduced side
lobe levels, microstrip band stop filter, microstrip band pass filter, coplanar waveguide band stop
filter, coplanar ultra-wide band antenna, and ultra-wide band antenna with band notch feature.
Satisfactory results obtained from the design process demonstrate the validity and efficiency
of the proposed Taguchi’s optimization method.
