Substrate Integrated Waveguide Filters for Microwave Communications

About the Book: In electronics filters are used to allow signals of a certain band of frequencies to pass while blocking others. They are a basic building block of electronic systems and have many applications. Amongst the uses of waveguide filters are the duplexers diplexers multiplexers selectivity and noise limitation in receivers and harmonic distortion suppression in transmitters. Waveguides are metal conduits used to confine and direct radio signals. Most commonly they are rectangular but other cross-sections as circular or elliptical also exist. A waveguide filter is a filter composed of waveguide components. It has the same range of applications as other filter technologies in electronics and radio engineering but is different mechanically and in its principle of operation. Waveguide filters have more in common with transmission line filters than lumped element filters; they do not contain any discrete capacitors or inductors. However the waveguide design may frequently be equivalent to a lumped element design. The design of waveguide filters frequently starts from a lumped element design and then converts the elements of that design into waveguide components. Starting with basic research on the developed in the recent years this book focuses on the simulation and building up of multiple Substrate Integrated Waveguide filters with multiple defined substrates About the Author: Dr. Aman Dahiya is working as an Assistant Professor in the Department of Electronics and Communication Engineering at Maharaja Surajmal Institute of Technology New Delhi.
