Inhaltsangabe

This book will appeal to scientists and engineers who are concerned with the design of microwave wideband devices and systems. For advanced (ultra)-wideband wireless systems, the necessity and design methodology of wideband filters will be discussed with reference to the inherent limitation in fractional bandwidth of classical bandpass filters. Besides the detailed working principles, a large number of design examples are demonstrated, which can be easily followed and modified by the readers to achieve their own desired specifications. Therefore, this book is of interest not only to students and researchers from academia, but also to design engineers in industry. With the help of complete design procedures and tabulated design parameters, even those with little filter design experience, will find this book to be a useful design guideline and reference, which can free them from tedious computer-aided full-wave electromagnetic simulations. Among different design proposals, wideband bandpass filters based on the multi-mode resonator have demonstrated many unparalleled attractive features, including a simple design methodology, compact size, low loss and good linearity in the wide passband, enhanced out-of-band rejection, and easy integration with other circuits/antennas. A conventional bandpass filter works under single dominant resonant modes of a few cascaded transmission line resonators and its operating bandwidth is widened via enhanced coupling between the adjacent resonators. However, this traditional approach needs an extremely high coupling degree of coupled-lines while producing a narrow upper stopband between the dominant and harmonic bands. As a sequence, the desired dominant passband is restricted to an extent less than 60% in fractional bandwidth. To circumvent these issues and break with the tradition, a filter based on the multiple resonant modes was initially introduced in 2000 by the first author of this book. Based on this novel concept, a new class of wideband filters with fractional bandwidths larger than 60% has been successfully developed so far. This book, presents and characterizes a variety of multi-mode resonators with stepped-impedance or loaded-stub configurations using the matured transmission line theory for development of advanced microwave wideband filters.

A Much-Needed Systematic Guide to the Design of (Ultra-)Wideband Bandpass Filters

Ultra-wideband (UWB) technology has attracted a lot of attention in recent years, owing to its numerous applications in high-speed and high-capacity wireless communications. At the same time, conventional synthesis methodologies were shown to be inadequate for bandpass filtering design covering a wide or ultra-wide bandpass. This book responds to the need for a practical guide to emerging design techniques for advanced (ultra-)wideband bandpass filters.

The authors introduce microwave wideband bandpass filter design theory using the multiple-mode resonator (MMR) along with the alternative synthesis design method for wideband bandpass filters, particularly for filters with FCC-defined UWB frequencies from 3.1 to 10.6 GHz. They demonstrate the application of both methods in the design of (ultra-)wideband bandpass filters, showing how to use these methods to implement filters in different frequencies and materials, calculate initial dimensions for various filter configurations, and more.

Special features of this book include:

  • Complete design procedures and tabulated design parameters for both MMR and the synthesis design method

  • A large number of easy-to-follow design examples, which can be modified by readers to achieve their own design specifications

  • Coverage of the basics, including transmission line theories and comparison with the design of conventional narrow-band bandpass filters

Microwave Bandpass Filters for Wideband Communications is an invaluable guide for researchers and engineers wishing to improve their design cycle and filter performance. It is also a useful reference for newcomers to the field, who wish to gain a better understanding of (ultra-)wideband bandpass design theory.
