SYNTHESIS LECTURES ON COMPUTATIONAL ELECTROMAGN...

Substrate integrated waveguide (SIW) is a new type of transmission line. It implements a
waveguide on a piece of printed circuit board by emulating the side walls of the waveguide
using two rows of metal posts. It inherits the merits both from the microstrip for compact size
and easy integration  and from the waveguide for low radiation loss  and thus opens another
door to design efficient microwave circuits and antennas at a low cost. This book presents a
two-dimensional fullwave analysis method to investigate an SIW circuit composed of metal and
dielectric posts. It combines the cylindrical eigenfunction expansion and the method of moments
to avoid geometrical descritization of the posts. The method is presented step-by-step  with
all the necessary formulations provided for a practitioner who wants to implement this method
by himself. This book covers the SIW circuit printed on either homogeneous or inhomogeneous
substrate  the microstrip-to-SIW transition and the speed-up technique for the simulation of
symmetrical SIW circuits. Different types of SIW circuits are shown and simulated using the
proposed method. In addition  several slot antennas and horn antennas fabricated using the SIW
technology are also given. Table of Contents: Introduction   SIW Circuits Composed of Metallic
Posts   SIW Circuits with Dielectric Posts   Even-Odd Mode Analysis of a Symmetrical Circuit  
Microstrip to SIW Transition and Half Mode SIW   SIW Antennas
